Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509986, here are decompositions:

17 + 33509969 = 33509986
173 + 33509813 = 33509986
353 + 33509633 = 33509986
383 + 33509603 = 33509986
557 + 33509429 = 33509986
569 + 33509417 = 33509986
593 + 33509393 = 33509986
659 + 33509327 = 33509986

Showing the first eight; more decompositions exist.
