Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585652, here are decompositions:

3 + 31585649 = 31585652
73 + 31585579 = 31585652
103 + 31585549 = 31585652
151 + 31585501 = 31585652
193 + 31585459 = 31585652
199 + 31585453 = 31585652
211 + 31585441 = 31585652
283 + 31585369 = 31585652

Showing the first eight; more decompositions exist.
