Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627056, here are decompositions:

5 + 31627051 = 31627056
23 + 31627033 = 31627056
29 + 31627027 = 31627056
79 + 31626977 = 31627056
89 + 31626967 = 31627056
113 + 31626943 = 31627056
157 + 31626899 = 31627056
163 + 31626893 = 31627056

Showing the first eight; more decompositions exist.
