Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585964, here are decompositions:

61 + 31585903 = 31585964
127 + 31585837 = 31585964
181 + 31585783 = 31585964
367 + 31585597 = 31585964
463 + 31585501 = 31585964
523 + 31585441 = 31585964
997 + 31584967 = 31585964
1063 + 31584901 = 31585964

Showing the first eight; more decompositions exist.
