Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622514, here are decompositions:

5 + 31622509 = 31622514
23 + 31622491 = 31622514
41 + 31622473 = 31622514
47 + 31622467 = 31622514
137 + 31622377 = 31622514
167 + 31622347 = 31622514
227 + 31622287 = 31622514
233 + 31622281 = 31622514

Showing the first eight; more decompositions exist.
