Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622902, here are decompositions:

173 + 31622729 = 31622902
239 + 31622663 = 31622902
383 + 31622519 = 31622902
719 + 31622183 = 31622902
761 + 31622141 = 31622902
821 + 31622081 = 31622902
953 + 31621949 = 31622902
1163 + 31621739 = 31622902

Showing the first eight; more decompositions exist.
