Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595912, here are decompositions:

31 + 31595881 = 31595912
43 + 31595869 = 31595912
79 + 31595833 = 31595912
181 + 31595731 = 31595912
193 + 31595719 = 31595912
211 + 31595701 = 31595912
241 + 31595671 = 31595912
331 + 31595581 = 31595912

Showing the first eight; more decompositions exist.
