Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533732, here are decompositions:

11 + 31533721 = 31533732
71 + 31533661 = 31533732
73 + 31533659 = 31533732
101 + 31533631 = 31533732
151 + 31533581 = 31533732
199 + 31533533 = 31533732
233 + 31533499 = 31533732
271 + 31533461 = 31533732

Showing the first eight; more decompositions exist.
