Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515228, here are decompositions:

151 + 33515077 = 33515228
619 + 33514609 = 33515228
631 + 33514597 = 33515228
751 + 33514477 = 33515228
829 + 33514399 = 33515228
1051 + 33514177 = 33515228
1129 + 33514099 = 33515228
1171 + 33514057 = 33515228

Showing the first eight; more decompositions exist.
