Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627190, here are decompositions:

139 + 31627051 = 31627190
157 + 31627033 = 31627190
163 + 31627027 = 31627190
211 + 31626979 = 31627190
223 + 31626967 = 31627190
307 + 31626883 = 31627190
349 + 31626841 = 31627190
499 + 31626691 = 31627190

Showing the first eight; more decompositions exist.
