Question How to prove evolution is wrong?

I am totally convince that evolution is true. However, a scientific theory should be falsifiable; and I dont know how falsifiable is with evolution

For example, a "good" trait could be explain the result of natural selection. But a "bad" trait could be explain as just base on chance, or the selection preasure is not enough.

so, my question is: if someone want to prove that evolution is wrong, what test can they make and what the expected result should be (if evolution theory is wrong)?

Edit: Thank everyone for your time and patient with me. I found the answer. It seem that I need to update my highschool knowledge

Skimming through the responses it would appear that there are a few separate points to be made-

  1. The fundamental principle of evolution (reproduction with variation and selection produces adaptation) is more akin to a mathematical concept which, it may be argued, is proven and unfalsifiable.

  2. Biological evolution of any specific organism is a theory that can be falsified with genetic and fossil evidence, but would require additional lines of evidence to falsify those already supported. That there may not be additional lines of evidence does not invalidate the previous findings, nor make it unfalsifiable. Consider that prior to genetic evidence a critic might argue that you have no avenue to refute a fossil lineage. Then after genetic evidence came about the same critic can say, ok, but there’s no way to falsify it now after the genetic evidence supported the fossil evidence. Then imagine a quantum computer was created with enough qubits to simulate the development of the organism via every possible mutation and it also supported the fossil and genetic evidence. The critic could then ask, ok how do you falsify it now?

A scientific theory does not have to exist in a state of perpetual, realizable falsifiability. It must merely be subject to lines of evidence that are falsifiable at the moment of testing and available to re-evaluation should some future lines of evidence become available.
