Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551550, here are decompositions:

7 + 33551543 = 33551550
17 + 33551533 = 33551550
23 + 33551527 = 33551550
31 + 33551519 = 33551550
37 + 33551513 = 33551550
41 + 33551509 = 33551550
89 + 33551461 = 33551550
101 + 33551449 = 33551550

Showing the first eight; more decompositions exist.
