Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510012, here are decompositions:

3 + 31510009 = 31510012
5 + 31510007 = 31510012
11 + 31510001 = 31510012
41 + 31509971 = 31510012
71 + 31509941 = 31510012
239 + 31509773 = 31510012
251 + 31509761 = 31510012
263 + 31509749 = 31510012

Showing the first eight; more decompositions exist.
