Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551518, here are decompositions:

5 + 33551513 = 33551518
17 + 33551501 = 33551518
59 + 33551459 = 33551518
101 + 33551417 = 33551518
149 + 33551369 = 33551518
257 + 33551261 = 33551518
269 + 33551249 = 33551518
281 + 33551237 = 33551518

Showing the first eight; more decompositions exist.
