Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477880, here are decompositions:

167 + 33477713 = 33477880
197 + 33477683 = 33477880
281 + 33477599 = 33477880
353 + 33477527 = 33477880
389 + 33477491 = 33477880
467 + 33477413 = 33477880
563 + 33477317 = 33477880
641 + 33477239 = 33477880

Showing the first eight; more decompositions exist.
