Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551920, here are decompositions:

11 + 33551909 = 33551920
47 + 33551873 = 33551920
53 + 33551867 = 33551920
71 + 33551849 = 33551920
137 + 33551783 = 33551920
179 + 33551741 = 33551920
293 + 33551627 = 33551920
401 + 33551519 = 33551920

Showing the first eight; more decompositions exist.
