Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596940, here are decompositions:

17 + 31596923 = 31596940
41 + 31596899 = 31596940
59 + 31596881 = 31596940
83 + 31596857 = 31596940
101 + 31596839 = 31596940
191 + 31596749 = 31596940
197 + 31596743 = 31596940
227 + 31596713 = 31596940

Showing the first eight; more decompositions exist.
