Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627110, here are decompositions:

19 + 31627091 = 31627110
37 + 31627073 = 31627110
41 + 31627069 = 31627110
59 + 31627051 = 31627110
83 + 31627027 = 31627110
103 + 31627007 = 31627110
131 + 31626979 = 31627110
167 + 31626943 = 31627110

Showing the first eight; more decompositions exist.
