Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551290, here are decompositions:

29 + 33551261 = 33551290
41 + 33551249 = 33551290
53 + 33551237 = 33551290
191 + 33551099 = 33551290
257 + 33551033 = 33551290
359 + 33550931 = 33551290
419 + 33550871 = 33551290
491 + 33550799 = 33551290

Showing the first eight; more decompositions exist.
