Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512618, here are decompositions:

151 + 33512467 = 33512618
199 + 33512419 = 33512618
211 + 33512407 = 33512618
397 + 33512221 = 33512618
757 + 33511861 = 33512618
829 + 33511789 = 33512618
991 + 33511627 = 33512618
1009 + 33511609 = 33512618

Showing the first eight; more decompositions exist.
