Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551820, here are decompositions:

19 + 33551801 = 33551820
23 + 33551797 = 33551820
37 + 33551783 = 33551820
47 + 33551773 = 33551820
61 + 33551759 = 33551820
79 + 33551741 = 33551820
83 + 33551737 = 33551820
89 + 33551731 = 33551820

Showing the first eight; more decompositions exist.
