Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585996, here are decompositions:

17 + 31585979 = 31585996
23 + 31585973 = 31585996
59 + 31585937 = 31585996
107 + 31585889 = 31585996
173 + 31585823 = 31585996
179 + 31585817 = 31585996
347 + 31585649 = 31585996
359 + 31585637 = 31585996

Showing the first eight; more decompositions exist.
