Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595864, here are decompositions:

31 + 31595833 = 31595864
163 + 31595701 = 31595864
193 + 31595671 = 31595864
211 + 31595653 = 31595864
271 + 31595593 = 31595864
283 + 31595581 = 31595864
397 + 31595467 = 31595864
457 + 31595407 = 31595864

Showing the first eight; more decompositions exist.
