Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585696, here are decompositions:

5 + 31585691 = 31585696
29 + 31585667 = 31585696
47 + 31585649 = 31585696
59 + 31585637 = 31585696
83 + 31585613 = 31585696
113 + 31585583 = 31585696
167 + 31585529 = 31585696
179 + 31585517 = 31585696

Showing the first eight; more decompositions exist.
