Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549728, here are decompositions:

61 + 33549667 = 33549728
67 + 33549661 = 33549728
97 + 33549631 = 33549728
127 + 33549601 = 33549728
151 + 33549577 = 33549728
379 + 33549349 = 33549728
409 + 33549319 = 33549728
439 + 33549289 = 33549728

Showing the first eight; more decompositions exist.
