Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595670, here are decompositions:

13 + 31595657 = 31595670
17 + 31595653 = 31595670
59 + 31595611 = 31595670
89 + 31595581 = 31595670
97 + 31595573 = 31595670
101 + 31595569 = 31595670
103 + 31595567 = 31595670
263 + 31595407 = 31595670

Showing the first eight; more decompositions exist.
