Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595832, here are decompositions:

61 + 31595771 = 31595832
101 + 31595731 = 31595832
109 + 31595723 = 31595832
113 + 31595719 = 31595832
131 + 31595701 = 31595832
179 + 31595653 = 31595832
239 + 31595593 = 31595832
251 + 31595581 = 31595832

Showing the first eight; more decompositions exist.
