Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514130, here are decompositions:

17 + 31514113 = 31514130
29 + 31514101 = 31514130
71 + 31514059 = 31514130
107 + 31514023 = 31514130
163 + 31513967 = 31514130
173 + 31513957 = 31514130
239 + 31513891 = 31514130
251 + 31513879 = 31514130

Showing the first eight; more decompositions exist.
