Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508560, here are decompositions:

11 + 33508549 = 33508560
53 + 33508507 = 33508560
61 + 33508499 = 33508560
73 + 33508487 = 33508560
89 + 33508471 = 33508560
97 + 33508463 = 33508560
199 + 33508361 = 33508560
227 + 33508333 = 33508560

Showing the first eight; more decompositions exist.
