Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510016, here are decompositions:

7 + 31510009 = 31510016
67 + 31509949 = 31510016
103 + 31509913 = 31510016
127 + 31509889 = 31510016
199 + 31509817 = 31510016
277 + 31509739 = 31510016
463 + 31509553 = 31510016
487 + 31509529 = 31510016

Showing the first eight; more decompositions exist.
