Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585692, here are decompositions:

29 + 31585663 = 31585692
43 + 31585649 = 31585692
79 + 31585613 = 31585692
109 + 31585583 = 31585692
113 + 31585579 = 31585692
163 + 31585529 = 31585692
191 + 31585501 = 31585692
199 + 31585493 = 31585692

Showing the first eight; more decompositions exist.
