Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627124, here are decompositions:

3 + 31627121 = 31627124
73 + 31627051 = 31627124
97 + 31627027 = 31627124
157 + 31626967 = 31627124
181 + 31626943 = 31627124
241 + 31626883 = 31627124
283 + 31626841 = 31627124
337 + 31626787 = 31627124

Showing the first eight; more decompositions exist.
