Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551428, here are decompositions:

11 + 33551417 = 33551428
59 + 33551369 = 33551428
167 + 33551261 = 33551428
179 + 33551249 = 33551428
191 + 33551237 = 33551428
257 + 33551171 = 33551428
461 + 33550967 = 33551428
479 + 33550949 = 33551428

Showing the first eight; more decompositions exist.
