Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551278, here are decompositions:

17 + 33551261 = 33551278
29 + 33551249 = 33551278
41 + 33551237 = 33551278
107 + 33551171 = 33551278
149 + 33551129 = 33551278
179 + 33551099 = 33551278
191 + 33551087 = 33551278
311 + 33550967 = 33551278

Showing the first eight; more decompositions exist.
