Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509550, here are decompositions:

23 + 33509527 = 33509550
89 + 33509461 = 33509550
149 + 33509401 = 33509550
157 + 33509393 = 33509550
197 + 33509353 = 33509550
223 + 33509327 = 33509550
227 + 33509323 = 33509550
271 + 33509279 = 33509550

Showing the first eight; more decompositions exist.
