Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513720, here are decompositions:

7 + 33513713 = 33513720
13 + 33513707 = 33513720
47 + 33513673 = 33513720
59 + 33513661 = 33513720
61 + 33513659 = 33513720
89 + 33513631 = 33513720
109 + 33513611 = 33513720
139 + 33513581 = 33513720

Showing the first eight; more decompositions exist.
