Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551478, here are decompositions:

17 + 33551461 = 33551478
19 + 33551459 = 33551478
29 + 33551449 = 33551478
61 + 33551417 = 33551478
101 + 33551377 = 33551478
109 + 33551369 = 33551478
179 + 33551299 = 33551478
229 + 33551249 = 33551478

Showing the first eight; more decompositions exist.
