Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549440, here are decompositions:

13 + 33549427 = 33549440
37 + 33549403 = 33549440
103 + 33549337 = 33549440
151 + 33549289 = 33549440
157 + 33549283 = 33549440
241 + 33549199 = 33549440
271 + 33549169 = 33549440
313 + 33549127 = 33549440

Showing the first eight; more decompositions exist.
