Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513128, here are decompositions:

31 + 33513097 = 33513128
151 + 33512977 = 33513128
199 + 33512929 = 33513128
349 + 33512779 = 33513128
457 + 33512671 = 33513128
487 + 33512641 = 33513128
499 + 33512629 = 33513128
661 + 33512467 = 33513128

Showing the first eight; more decompositions exist.
