Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508518, here are decompositions:

11 + 33508507 = 33508518
19 + 33508499 = 33508518
31 + 33508487 = 33508518
47 + 33508471 = 33508518
101 + 33508417 = 33508518
157 + 33508361 = 33508518
179 + 33508339 = 33508518
227 + 33508291 = 33508518

Showing the first eight; more decompositions exist.
