Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515720, here are decompositions:

13 + 33515707 = 33515720
19 + 33515701 = 33515720
103 + 33515617 = 33515720
127 + 33515593 = 33515720
151 + 33515569 = 33515720
181 + 33515539 = 33515720
211 + 33515509 = 33515720
283 + 33515437 = 33515720

Showing the first eight; more decompositions exist.
