Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512180, here are decompositions:

43 + 33512137 = 33512180
67 + 33512113 = 33512180
127 + 33512053 = 33512180
241 + 33511939 = 33512180
463 + 33511717 = 33512180
487 + 33511693 = 33512180
571 + 33511609 = 33512180
619 + 33511561 = 33512180

Showing the first eight; more decompositions exist.
