Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622636, here are decompositions:

7 + 31622629 = 31622636
37 + 31622599 = 31622636
127 + 31622509 = 31622636
163 + 31622473 = 31622636
349 + 31622287 = 31622636
379 + 31622257 = 31622636
457 + 31622179 = 31622636
523 + 31622113 = 31622636

Showing the first eight; more decompositions exist.
