Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33546640, here are decompositions:

11 + 33546629 = 33546640
41 + 33546599 = 33546640
89 + 33546551 = 33546640
167 + 33546473 = 33546640
227 + 33546413 = 33546640
311 + 33546329 = 33546640
359 + 33546281 = 33546640
389 + 33546251 = 33546640

Showing the first eight; more decompositions exist.
