Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549380, here are decompositions:

3 + 33549377 = 33549380
31 + 33549349 = 33549380
43 + 33549337 = 33549380
61 + 33549319 = 33549380
97 + 33549283 = 33549380
127 + 33549253 = 33549380
181 + 33549199 = 33549380
211 + 33549169 = 33549380

Showing the first eight; more decompositions exist.
