Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549640, here are decompositions:

41 + 33549599 = 33549640
71 + 33549569 = 33549640
83 + 33549557 = 33549640
263 + 33549377 = 33549640
281 + 33549359 = 33549640
317 + 33549323 = 33549640
359 + 33549281 = 33549640
389 + 33549251 = 33549640

Showing the first eight; more decompositions exist.
