Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509540, here are decompositions:

13 + 33509527 = 33509540
79 + 33509461 = 33509540
139 + 33509401 = 33509540
151 + 33509389 = 33509540
271 + 33509269 = 33509540
283 + 33509257 = 33509540
331 + 33509209 = 33509540
367 + 33509173 = 33509540

Showing the first eight; more decompositions exist.
