Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608640, here are decompositions:

11 + 33608629 = 33608640
29 + 33608611 = 33608640
59 + 33608581 = 33608640
61 + 33608579 = 33608640
71 + 33608569 = 33608640
73 + 33608567 = 33608640
101 + 33608539 = 33608640
113 + 33608527 = 33608640

Showing the first eight; more decompositions exist.
