Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596946, here are decompositions:

23 + 31596923 = 31596946
47 + 31596899 = 31596946
89 + 31596857 = 31596946
107 + 31596839 = 31596946
149 + 31596797 = 31596946
197 + 31596749 = 31596946
233 + 31596713 = 31596946
239 + 31596707 = 31596946

Showing the first eight; more decompositions exist.
