Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510088, here are decompositions:

67 + 31510021 = 31510088
79 + 31510009 = 31510088
97 + 31509991 = 31510088
139 + 31509949 = 31510088
199 + 31509889 = 31510088
271 + 31509817 = 31510088
307 + 31509781 = 31510088
331 + 31509757 = 31510088

Showing the first eight; more decompositions exist.
