Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511176, here are decompositions:

5 + 31511171 = 31511176
29 + 31511147 = 31511176
107 + 31511069 = 31511176
173 + 31511003 = 31511176
419 + 31510757 = 31511176
659 + 31510517 = 31511176
743 + 31510433 = 31511176
773 + 31510403 = 31511176

Showing the first eight; more decompositions exist.
