Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549820, here are decompositions:

23 + 33549797 = 33549820
41 + 33549779 = 33549820
47 + 33549773 = 33549820
137 + 33549683 = 33549820
149 + 33549671 = 33549820
251 + 33549569 = 33549820
257 + 33549563 = 33549820
263 + 33549557 = 33549820

Showing the first eight; more decompositions exist.
