Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585796, here are decompositions:

13 + 31585783 = 31585796
19 + 31585777 = 31585796
199 + 31585597 = 31585796
337 + 31585459 = 31585796
349 + 31585447 = 31585796
397 + 31585399 = 31585796
457 + 31585339 = 31585796
607 + 31585189 = 31585796

Showing the first eight; more decompositions exist.
