Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510774, here are decompositions:

3 + 31510771 = 31510774
5 + 31510769 = 31510774
11 + 31510763 = 31510774
17 + 31510757 = 31510774
83 + 31510691 = 31510774
233 + 31510541 = 31510774
257 + 31510517 = 31510774
557 + 31510217 = 31510774

Showing the first eight; more decompositions exist.
