Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626224, here are decompositions:

31 + 31626193 = 31626224
151 + 31626073 = 31626224
271 + 31625953 = 31626224
307 + 31625917 = 31626224
313 + 31625911 = 31626224
457 + 31625767 = 31626224
463 + 31625761 = 31626224
571 + 31625653 = 31626224

Showing the first eight; more decompositions exist.
