Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596718, here are decompositions:

5 + 31596713 = 31596718
11 + 31596707 = 31596718
47 + 31596671 = 31596718
107 + 31596611 = 31596718
281 + 31596437 = 31596718
317 + 31596401 = 31596718
401 + 31596317 = 31596718
509 + 31596209 = 31596718

Showing the first eight; more decompositions exist.
