Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596712, here are decompositions:

3 + 31596709 = 31596712
5 + 31596707 = 31596712
41 + 31596671 = 31596712
101 + 31596611 = 31596712
239 + 31596473 = 31596712
293 + 31596419 = 31596712
311 + 31596401 = 31596712
401 + 31596311 = 31596712

Showing the first eight; more decompositions exist.
