Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595810, here are decompositions:

3 + 31595807 = 31595810
79 + 31595731 = 31595810
109 + 31595701 = 31595810
139 + 31595671 = 31595810
157 + 31595653 = 31595810
199 + 31595611 = 31595810
229 + 31595581 = 31595810
241 + 31595569 = 31595810

Showing the first eight; more decompositions exist.
