Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627094, here are decompositions:

3 + 31627091 = 31627094
43 + 31627051 = 31627094
61 + 31627033 = 31627094
67 + 31627027 = 31627094
127 + 31626967 = 31627094
151 + 31626943 = 31627094
211 + 31626883 = 31627094
307 + 31626787 = 31627094

Showing the first eight; more decompositions exist.
