Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533764, here are decompositions:

43 + 31533721 = 31533764
103 + 31533661 = 31533764
127 + 31533637 = 31533764
151 + 31533613 = 31533764
193 + 31533571 = 31533764
313 + 31533451 = 31533764
421 + 31533343 = 31533764
631 + 31533133 = 31533764

Showing the first eight; more decompositions exist.
