Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585764, here are decompositions:

13 + 31585751 = 31585764
73 + 31585691 = 31585764
97 + 31585667 = 31585764
101 + 31585663 = 31585764
127 + 31585637 = 31585764
151 + 31585613 = 31585764
167 + 31585597 = 31585764
181 + 31585583 = 31585764

Showing the first eight; more decompositions exist.
