Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585126, here are decompositions:

47 + 31585079 = 31585126
59 + 31585067 = 31585126
107 + 31585019 = 31585126
173 + 31584953 = 31585126
179 + 31584947 = 31585126
239 + 31584887 = 31585126
257 + 31584869 = 31585126
317 + 31584809 = 31585126

Showing the first eight; more decompositions exist.
