Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33611640, here are decompositions:

11 + 33611629 = 33611640
19 + 33611621 = 33611640
37 + 33611603 = 33611640
67 + 33611573 = 33611640
79 + 33611561 = 33611640
103 + 33611537 = 33611640
151 + 33611489 = 33611640
157 + 33611483 = 33611640

Showing the first eight; more decompositions exist.
