Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510070, here are decompositions:

61 + 31510009 = 31510070
79 + 31509991 = 31510070
103 + 31509967 = 31510070
157 + 31509913 = 31510070
181 + 31509889 = 31510070
307 + 31509763 = 31510070
313 + 31509757 = 31510070
331 + 31509739 = 31510070

Showing the first eight; more decompositions exist.
