Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596756, here are decompositions:

5 + 31596751 = 31596756
7 + 31596749 = 31596756
13 + 31596743 = 31596756
43 + 31596713 = 31596756
47 + 31596709 = 31596756
83 + 31596673 = 31596756
173 + 31596583 = 31596756
283 + 31596473 = 31596756

Showing the first eight; more decompositions exist.
