Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513782, here are decompositions:

109 + 33513673 = 33513782
151 + 33513631 = 33513782
223 + 33513559 = 33513782
241 + 33513541 = 33513782
283 + 33513499 = 33513782
409 + 33513373 = 33513782
439 + 33513343 = 33513782
619 + 33513163 = 33513782

Showing the first eight; more decompositions exist.
