Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509660, here are decompositions:

13 + 33509647 = 33509660
43 + 33509617 = 33509660
199 + 33509461 = 33509660
271 + 33509389 = 33509660
307 + 33509353 = 33509660
337 + 33509323 = 33509660
487 + 33509173 = 33509660
619 + 33509041 = 33509660

Showing the first eight; more decompositions exist.
