Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586122, here are decompositions:

149 + 31585973 = 31586122
233 + 31585889 = 31586122
311 + 31585811 = 31586122
431 + 31585691 = 31586122
509 + 31585613 = 31586122
593 + 31585529 = 31586122
653 + 31585469 = 31586122
761 + 31585361 = 31586122

Showing the first eight; more decompositions exist.
