Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585596, here are decompositions:

13 + 31585583 = 31585596
17 + 31585579 = 31585596
19 + 31585577 = 31585596
47 + 31585549 = 31585596
59 + 31585537 = 31585596
67 + 31585529 = 31585596
79 + 31585517 = 31585596
103 + 31585493 = 31585596

Showing the first eight; more decompositions exist.
