Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622206, here are decompositions:

17 + 31622189 = 31622206
23 + 31622183 = 31622206
53 + 31622153 = 31622206
59 + 31622147 = 31622206
227 + 31621979 = 31622206
257 + 31621949 = 31622206
359 + 31621847 = 31622206
467 + 31621739 = 31622206

Showing the first eight; more decompositions exist.
