Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122756, here are decompositions:

3 + 122753 = 122756
13 + 122743 = 122756
37 + 122719 = 122756
103 + 122653 = 122756
157 + 122599 = 122756
199 + 122557 = 122756
223 + 122533 = 122756
229 + 122527 = 122756

Showing the first eight; more decompositions exist.
