Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549520, here are decompositions:

89 + 33549431 = 33549520
167 + 33549353 = 33549520
197 + 33549323 = 33549520
239 + 33549281 = 33549520
269 + 33549251 = 33549520
281 + 33549239 = 33549520
293 + 33549227 = 33549520
383 + 33549137 = 33549520

Showing the first eight; more decompositions exist.
