Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510056, here are decompositions:

47 + 31510009 = 31510056
89 + 31509967 = 31510056
107 + 31509949 = 31510056
163 + 31509893 = 31510056
167 + 31509889 = 31510056
173 + 31509883 = 31510056
239 + 31509817 = 31510056
283 + 31509773 = 31510056

Showing the first eight; more decompositions exist.
