Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513640, here are decompositions:

11 + 33513629 = 33513640
29 + 33513611 = 33513640
59 + 33513581 = 33513640
71 + 33513569 = 33513640
89 + 33513551 = 33513640
101 + 33513539 = 33513640
107 + 33513533 = 33513640
131 + 33513509 = 33513640

Showing the first eight; more decompositions exist.
