Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595732, here are decompositions:

13 + 31595719 = 31595732
31 + 31595701 = 31595732
61 + 31595671 = 31595732
79 + 31595653 = 31595732
139 + 31595593 = 31595732
151 + 31595581 = 31595732
163 + 31595569 = 31595732
349 + 31595383 = 31595732

Showing the first eight; more decompositions exist.
