Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622660, here are decompositions:

19 + 31622641 = 31622660
31 + 31622629 = 31622660
61 + 31622599 = 31622660
151 + 31622509 = 31622660
193 + 31622467 = 31622660
271 + 31622389 = 31622660
283 + 31622377 = 31622660
313 + 31622347 = 31622660

Showing the first eight; more decompositions exist.
