Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595724, here are decompositions:

5 + 31595719 = 31595724
7 + 31595717 = 31595724
23 + 31595701 = 31595724
37 + 31595687 = 31595724
53 + 31595671 = 31595724
67 + 31595657 = 31595724
71 + 31595653 = 31595724
113 + 31595611 = 31595724

Showing the first eight; more decompositions exist.
