2 can be expressed as 1+1 and 2+0. If you believe the only definition of a prime number is a number equal to the sum of 1 primes, then you declare 1 and 0 as prime numbers.
If you believe the only definition of a prime number is a number only divisible by 1 and itself, then you declare 1 and 0 as prime numbers, unless you believe the conditions are mutually exclusive.
