Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622176, here are decompositions:

23 + 31622153 = 31622176
29 + 31622147 = 31622176
197 + 31621979 = 31622176
227 + 31621949 = 31622176
503 + 31621673 = 31622176
563 + 31621613 = 31622176
617 + 31621559 = 31622176
659 + 31621517 = 31622176

Showing the first eight; more decompositions exist.
