Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551538, here are decompositions:

5 + 33551533 = 33551538
11 + 33551527 = 33551538
19 + 33551519 = 33551538
29 + 33551509 = 33551538
37 + 33551501 = 33551538
79 + 33551459 = 33551538
89 + 33551449 = 33551538
239 + 33551299 = 33551538

Showing the first eight; more decompositions exist.
