Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622344, here are decompositions:

71 + 31622273 = 31622344
107 + 31622237 = 31622344
137 + 31622207 = 31622344
191 + 31622153 = 31622344
197 + 31622147 = 31622344
263 + 31622081 = 31622344
443 + 31621901 = 31622344
641 + 31621703 = 31622344

Showing the first eight; more decompositions exist.
