Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551808, here are decompositions:

7 + 33551801 = 33551808
11 + 33551797 = 33551808
67 + 33551741 = 33551808
71 + 33551737 = 33551808
89 + 33551719 = 33551808
131 + 33551677 = 33551808
179 + 33551629 = 33551808
181 + 33551627 = 33551808

Showing the first eight; more decompositions exist.
