Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510046, here are decompositions:

37 + 31510009 = 31510046
79 + 31509967 = 31510046
97 + 31509949 = 31510046
157 + 31509889 = 31510046
163 + 31509883 = 31510046
229 + 31509817 = 31510046
283 + 31509763 = 31510046
307 + 31509739 = 31510046

Showing the first eight; more decompositions exist.
