Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585460, here are decompositions:

7 + 31585453 = 31585460
13 + 31585447 = 31585460
19 + 31585441 = 31585460
61 + 31585399 = 31585460
199 + 31585261 = 31585460
271 + 31585189 = 31585460
367 + 31585093 = 31585460
499 + 31584961 = 31585460

Showing the first eight; more decompositions exist.
