Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549478, here are decompositions:

47 + 33549431 = 33549478
101 + 33549377 = 33549478
167 + 33549311 = 33549478
197 + 33549281 = 33549478
227 + 33549251 = 33549478
239 + 33549239 = 33549478
251 + 33549227 = 33549478
257 + 33549221 = 33549478

Showing the first eight; more decompositions exist.
