Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549808, here are decompositions:

11 + 33549797 = 33549808
29 + 33549779 = 33549808
137 + 33549671 = 33549808
239 + 33549569 = 33549808
251 + 33549557 = 33549808
431 + 33549377 = 33549808
449 + 33549359 = 33549808
557 + 33549251 = 33549808

Showing the first eight; more decompositions exist.
