Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497920, here are decompositions:

47 + 33497873 = 33497920
101 + 33497819 = 33497920
167 + 33497753 = 33497920
173 + 33497747 = 33497920
233 + 33497687 = 33497920
263 + 33497657 = 33497920
311 + 33497609 = 33497920
317 + 33497603 = 33497920

Showing the first eight; more decompositions exist.
