Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551660, here are decompositions:

31 + 33551629 = 33551660
67 + 33551593 = 33551660
127 + 33551533 = 33551660
151 + 33551509 = 33551660
199 + 33551461 = 33551660
211 + 33551449 = 33551660
283 + 33551377 = 33551660
547 + 33551113 = 33551660

Showing the first eight; more decompositions exist.
