Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33473748, here are decompositions:

67 + 33473681 = 33473748
71 + 33473677 = 33473748
149 + 33473599 = 33473748
197 + 33473551 = 33473748
199 + 33473549 = 33473748
281 + 33473467 = 33473748
311 + 33473437 = 33473748
317 + 33473431 = 33473748

Showing the first eight; more decompositions exist.
