Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622212, here are decompositions:

5 + 31622207 = 31622212
23 + 31622189 = 31622212
29 + 31622183 = 31622212
59 + 31622153 = 31622212
71 + 31622141 = 31622212
131 + 31622081 = 31622212
233 + 31621979 = 31622212
263 + 31621949 = 31622212

Showing the first eight; more decompositions exist.
