Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551728, here are decompositions:

11 + 33551717 = 33551728
101 + 33551627 = 33551728
227 + 33551501 = 33551728
269 + 33551459 = 33551728
311 + 33551417 = 33551728
359 + 33551369 = 33551728
467 + 33551261 = 33551728
479 + 33551249 = 33551728

Showing the first eight; more decompositions exist.
