Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514126, here are decompositions:

13 + 31514113 = 31514126
67 + 31514059 = 31514126
103 + 31514023 = 31514126
139 + 31513987 = 31514126
199 + 31513927 = 31514126
277 + 31513849 = 31514126
283 + 31513843 = 31514126
307 + 31513819 = 31514126

Showing the first eight; more decompositions exist.
