Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585822, here are decompositions:

5 + 31585817 = 31585822
11 + 31585811 = 31585822
41 + 31585781 = 31585822
71 + 31585751 = 31585822
131 + 31585691 = 31585822
173 + 31585649 = 31585822
239 + 31585583 = 31585822
251 + 31585571 = 31585822

Showing the first eight; more decompositions exist.
