Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509672, here are decompositions:

13 + 33509659 = 33509672
103 + 33509569 = 33509672
211 + 33509461 = 33509672
271 + 33509401 = 33509672
283 + 33509389 = 33509672
349 + 33509323 = 33509672
463 + 33509209 = 33509672
499 + 33509173 = 33509672

Showing the first eight; more decompositions exist.
