Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551780, here are decompositions:

7 + 33551773 = 33551780
43 + 33551737 = 33551780
61 + 33551719 = 33551780
103 + 33551677 = 33551780
151 + 33551629 = 33551780
271 + 33551509 = 33551780
331 + 33551449 = 33551780
463 + 33551317 = 33551780

Showing the first eight; more decompositions exist.
