Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596616, here are decompositions:

3 + 31596613 = 31596616
5 + 31596611 = 31596616
179 + 31596437 = 31596616
197 + 31596419 = 31596616
587 + 31596029 = 31596616
647 + 31595969 = 31596616
743 + 31595873 = 31596616
809 + 31595807 = 31596616

Showing the first eight; more decompositions exist.
