Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586956, here are decompositions:

17 + 31586939 = 31586956
29 + 31586927 = 31586956
53 + 31586903 = 31586956
239 + 31586717 = 31586956
257 + 31586699 = 31586956
419 + 31586537 = 31586956
509 + 31586447 = 31586956
617 + 31586339 = 31586956

Showing the first eight; more decompositions exist.
