Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551420, here are decompositions:

3 + 33551417 = 33551420
43 + 33551377 = 33551420
103 + 33551317 = 33551420
163 + 33551257 = 33551420
211 + 33551209 = 33551420
241 + 33551179 = 33551420
307 + 33551113 = 33551420
313 + 33551107 = 33551420

Showing the first eight; more decompositions exist.
