Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585762, here are decompositions:

11 + 31585751 = 31585762
71 + 31585691 = 31585762
113 + 31585649 = 31585762
149 + 31585613 = 31585762
179 + 31585583 = 31585762
191 + 31585571 = 31585762
233 + 31585529 = 31585762
269 + 31585493 = 31585762

Showing the first eight; more decompositions exist.
