Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510094, here are decompositions:

3 + 31510091 = 31510094
73 + 31510021 = 31510094
103 + 31509991 = 31510094
127 + 31509967 = 31510094
181 + 31509913 = 31510094
211 + 31509883 = 31510094
277 + 31509817 = 31510094
313 + 31509781 = 31510094

Showing the first eight; more decompositions exist.
