Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595682, here are decompositions:

11 + 31595671 = 31595682
29 + 31595653 = 31595682
71 + 31595611 = 31595682
89 + 31595593 = 31595682
101 + 31595581 = 31595682
109 + 31595573 = 31595682
113 + 31595569 = 31595682
199 + 31595483 = 31595682

Showing the first eight; more decompositions exist.
