Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511044, here are decompositions:

3 + 31511041 = 31511044
41 + 31511003 = 31511044
113 + 31510931 = 31511044
197 + 31510847 = 31511044
233 + 31510811 = 31511044
263 + 31510781 = 31511044
281 + 31510763 = 31511044
353 + 31510691 = 31511044

Showing the first eight; more decompositions exist.
