Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510034, here are decompositions:

13 + 31510021 = 31510034
43 + 31509991 = 31510034
67 + 31509967 = 31510034
151 + 31509883 = 31510034
271 + 31509763 = 31510034
277 + 31509757 = 31510034
337 + 31509697 = 31510034
373 + 31509661 = 31510034

Showing the first eight; more decompositions exist.
