Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513866, here are decompositions:

3 + 33513863 = 33513866
7 + 33513859 = 33513866
193 + 33513673 = 33513866
307 + 33513559 = 33513866
367 + 33513499 = 33513866
409 + 33513457 = 33513866
499 + 33513367 = 33513866
523 + 33513343 = 33513866

Showing the first eight; more decompositions exist.
