Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622708, here are decompositions:

37 + 31622671 = 31622708
67 + 31622641 = 31622708
79 + 31622629 = 31622708
109 + 31622599 = 31622708
199 + 31622509 = 31622708
241 + 31622467 = 31622708
331 + 31622377 = 31622708
421 + 31622287 = 31622708

Showing the first eight; more decompositions exist.
