Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586482, here are decompositions:

131 + 31586351 = 31586482
311 + 31586171 = 31586482
479 + 31586003 = 31586482
503 + 31585979 = 31586482
509 + 31585973 = 31586482
593 + 31585889 = 31586482
659 + 31585823 = 31586482
701 + 31585781 = 31586482

Showing the first eight; more decompositions exist.
