Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553680, here are decompositions:

19 + 33553661 = 33553680
23 + 33553657 = 33553680
29 + 33553651 = 33553680
31 + 33553649 = 33553680
47 + 33553633 = 33553680
67 + 33553613 = 33553680
73 + 33553607 = 33553680
103 + 33553577 = 33553680

Showing the first eight; more decompositions exist.
