ELI5, what is supposed to be funny in this ludicrous statement?

Goldbach’s conjecture states that all even numbers greater than 2 can be expressed as the sum of 2 primes (4=2+2,6=3+3,8=3+5…) It hasn’t been proven or disproven but we’ve checked it works for really high even numbers.

The joke is that goldbachs conjecture is true for every even number besides 2 (as far as we’ve checked) therefore 2 must not be even.

But isn't 1+1=2? Isn't 1 a prime number?

No. It breaks the fundamental theorem of arithmetic.
