Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586422, here are decompositions:

71 + 31586351 = 31586422
83 + 31586339 = 31586422
149 + 31586273 = 31586422
251 + 31586171 = 31586422
281 + 31586141 = 31586422
419 + 31586003 = 31586422
443 + 31585979 = 31586422
449 + 31585973 = 31586422

Showing the first eight; more decompositions exist.
