Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586764, here are decompositions:

47 + 31586717 = 31586764
137 + 31586627 = 31586764
173 + 31586591 = 31586764
227 + 31586537 = 31586764
263 + 31586501 = 31586764
281 + 31586483 = 31586764
317 + 31586447 = 31586764
491 + 31586273 = 31586764

Showing the first eight; more decompositions exist.
