Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586314, here are decompositions:

3 + 31586311 = 31586314
41 + 31586273 = 31586314
167 + 31586147 = 31586314
173 + 31586141 = 31586314
257 + 31586057 = 31586314
311 + 31586003 = 31586314
317 + 31585997 = 31586314
491 + 31585823 = 31586314

Showing the first eight; more decompositions exist.
