Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622164, here are decompositions:

11 + 31622153 = 31622164
17 + 31622147 = 31622164
23 + 31622141 = 31622164
83 + 31622081 = 31622164
263 + 31621901 = 31622164
317 + 31621847 = 31622164
461 + 31621703 = 31622164
491 + 31621673 = 31622164

Showing the first eight; more decompositions exist.
