Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596516, here are decompositions:

5 + 31596511 = 31596516
19 + 31596497 = 31596516
43 + 31596473 = 31596516
79 + 31596437 = 31596516
97 + 31596419 = 31596516
103 + 31596413 = 31596516
113 + 31596403 = 31596516
137 + 31596379 = 31596516

Showing the first eight; more decompositions exist.
