Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549818, here are decompositions:

61 + 33549757 = 33549818
151 + 33549667 = 33549818
157 + 33549661 = 33549818
241 + 33549577 = 33549818
277 + 33549541 = 33549818
307 + 33549511 = 33549818
499 + 33549319 = 33549818
619 + 33549199 = 33549818

Showing the first eight; more decompositions exist.
