Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512640, here are decompositions:

11 + 33512629 = 33512640
23 + 33512617 = 33512640
61 + 33512579 = 33512640
67 + 33512573 = 33512640
71 + 33512569 = 33512640
103 + 33512537 = 33512640
107 + 33512533 = 33512640
137 + 33512503 = 33512640

Showing the first eight; more decompositions exist.
