Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595310, here are decompositions:

31 + 31595279 = 31595310
37 + 31595273 = 31595310
59 + 31595251 = 31595310
67 + 31595243 = 31595310
73 + 31595237 = 31595310
101 + 31595209 = 31595310
137 + 31595173 = 31595310
251 + 31595059 = 31595310

Showing the first eight; more decompositions exist.
