Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627064, here are decompositions:

13 + 31627051 = 31627064
31 + 31627033 = 31627064
37 + 31627027 = 31627064
97 + 31626967 = 31627064
181 + 31626883 = 31627064
223 + 31626841 = 31627064
277 + 31626787 = 31627064
373 + 31626691 = 31627064

Showing the first eight; more decompositions exist.
