Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551878, here are decompositions:

5 + 33551873 = 33551878
11 + 33551867 = 33551878
29 + 33551849 = 33551878
137 + 33551741 = 33551878
251 + 33551627 = 33551878
359 + 33551519 = 33551878
419 + 33551459 = 33551878
461 + 33551417 = 33551878

Showing the first eight; more decompositions exist.
