Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585110, here are decompositions:

17 + 31585093 = 31585110
31 + 31585079 = 31585110
43 + 31585067 = 31585110
149 + 31584961 = 31585110
157 + 31584953 = 31585110
163 + 31584947 = 31585110
223 + 31584887 = 31585110
229 + 31584881 = 31585110

Showing the first eight; more decompositions exist.
