Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551680, here are decompositions:

3 + 33551677 = 33551680
53 + 33551627 = 33551680
137 + 33551543 = 33551680
167 + 33551513 = 33551680
179 + 33551501 = 33551680
263 + 33551417 = 33551680
311 + 33551369 = 33551680
317 + 33551363 = 33551680

Showing the first eight; more decompositions exist.
