Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622416, here are decompositions:

47 + 31622369 = 31622416
179 + 31622237 = 31622416
227 + 31622189 = 31622416
233 + 31622183 = 31622416
263 + 31622153 = 31622416
269 + 31622147 = 31622416
467 + 31621949 = 31622416
569 + 31621847 = 31622416

Showing the first eight; more decompositions exist.
