Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549518, here are decompositions:

7 + 33549511 = 33549518
181 + 33549337 = 33549518
199 + 33549319 = 33549518
229 + 33549289 = 33549518
349 + 33549169 = 33549518
577 + 33548941 = 33549518
601 + 33548917 = 33549518
661 + 33548857 = 33549518

Showing the first eight; more decompositions exist.
