A023036: Smallest positive even integer that is an unordered sum of two primes in exactly
n
ways.
{ 2, 4, 10, 22, 34, 48, 60, 78, 84, 90, ... }

Note that the offset of this sequence is 0. There are 0 ways to express 2 as an unordered sum of two primes. If the Goldbach conjecture is true, there is no other even integer with this property.
