Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551440, here are decompositions:

23 + 33551417 = 33551440
71 + 33551369 = 33551440
107 + 33551333 = 33551440
137 + 33551303 = 33551440
179 + 33551261 = 33551440
191 + 33551249 = 33551440
227 + 33551213 = 33551440
269 + 33551171 = 33551440

Showing the first eight; more decompositions exist.
