Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596738, here are decompositions:

29 + 31596709 = 31596738
31 + 31596707 = 31596738
59 + 31596679 = 31596738
67 + 31596671 = 31596738
101 + 31596637 = 31596738
127 + 31596611 = 31596738
167 + 31596571 = 31596738
197 + 31596541 = 31596738

Showing the first eight; more decompositions exist.
