Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551644, here are decompositions:

17 + 33551627 = 33551644
101 + 33551543 = 33551644
131 + 33551513 = 33551644
227 + 33551417 = 33551644
281 + 33551363 = 33551644
311 + 33551333 = 33551644
383 + 33551261 = 33551644
431 + 33551213 = 33551644

Showing the first eight; more decompositions exist.
