Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622610, here are decompositions:

11 + 31622599 = 31622610
31 + 31622579 = 31622610
73 + 31622537 = 31622610
101 + 31622509 = 31622610
137 + 31622473 = 31622610
181 + 31622429 = 31622610
233 + 31622377 = 31622610
241 + 31622369 = 31622610

Showing the first eight; more decompositions exist.
