Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626946, here are decompositions:

3 + 31626943 = 31626946
47 + 31626899 = 31626946
53 + 31626893 = 31626946
89 + 31626857 = 31626946
107 + 31626839 = 31626946
149 + 31626797 = 31626946
179 + 31626767 = 31626946
257 + 31626689 = 31626946

Showing the first eight; more decompositions exist.
