Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585096, here are decompositions:

3 + 31585093 = 31585096
17 + 31585079 = 31585096
29 + 31585067 = 31585096
149 + 31584947 = 31585096
227 + 31584869 = 31585096
383 + 31584713 = 31585096
443 + 31584653 = 31585096
479 + 31584617 = 31585096

Showing the first eight; more decompositions exist.
