Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595708, here are decompositions:

7 + 31595701 = 31595708
37 + 31595671 = 31595708
97 + 31595611 = 31595708
127 + 31595581 = 31595708
139 + 31595569 = 31595708
241 + 31595467 = 31595708
337 + 31595371 = 31595708
457 + 31595251 = 31595708

Showing the first eight; more decompositions exist.
