Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512720, here are decompositions:

67 + 33512653 = 33512720
79 + 33512641 = 33512720
103 + 33512617 = 33512720
151 + 33512569 = 33512720
313 + 33512407 = 33512720
337 + 33512383 = 33512720
421 + 33512299 = 33512720
457 + 33512263 = 33512720

Showing the first eight; more decompositions exist.
