Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551520, here are decompositions:

7 + 33551513 = 33551520
11 + 33551509 = 33551520
19 + 33551501 = 33551520
59 + 33551461 = 33551520
61 + 33551459 = 33551520
71 + 33551449 = 33551520
103 + 33551417 = 33551520
151 + 33551369 = 33551520

Showing the first eight; more decompositions exist.
