Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626948, here are decompositions:

5 + 31626943 = 31626948
79 + 31626869 = 31626948
107 + 31626841 = 31626948
109 + 31626839 = 31626948
151 + 31626797 = 31626948
181 + 31626767 = 31626948
239 + 31626709 = 31626948
257 + 31626691 = 31626948

Showing the first eight; more decompositions exist.
