Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551638, here are decompositions:

11 + 33551627 = 33551638
137 + 33551501 = 33551638
179 + 33551459 = 33551638
269 + 33551369 = 33551638
389 + 33551249 = 33551638
401 + 33551237 = 33551638
467 + 33551171 = 33551638
509 + 33551129 = 33551638

Showing the first eight; more decompositions exist.
