Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513440, here are decompositions:

19 + 33513421 = 33513440
67 + 33513373 = 33513440
73 + 33513367 = 33513440
97 + 33513343 = 33513440
193 + 33513247 = 33513440
277 + 33513163 = 33513440
307 + 33513133 = 33513440
313 + 33513127 = 33513440

Showing the first eight; more decompositions exist.
