Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543680, here are decompositions:

7 + 33543673 = 33543680
19 + 33543661 = 33543680
31 + 33543649 = 33543680
97 + 33543583 = 33543680
103 + 33543577 = 33543680
127 + 33543553 = 33543680
151 + 33543529 = 33543680
193 + 33543487 = 33543680

Showing the first eight; more decompositions exist.
