Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509478, here are decompositions:

17 + 33509461 = 33509478
61 + 33509417 = 33509478
89 + 33509389 = 33509478
151 + 33509327 = 33509478
199 + 33509279 = 33509478
269 + 33509209 = 33509478
349 + 33509129 = 33509478
439 + 33509039 = 33509478

Showing the first eight; more decompositions exist.
