Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513390, here are decompositions:

17 + 33513373 = 33513390
23 + 33513367 = 33513390
47 + 33513343 = 33513390
109 + 33513281 = 33513390
193 + 33513197 = 33513390
223 + 33513167 = 33513390
227 + 33513163 = 33513390
257 + 33513133 = 33513390

Showing the first eight; more decompositions exist.
