Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509420, here are decompositions:

3 + 33509417 = 33509420
19 + 33509401 = 33509420
31 + 33509389 = 33509420
67 + 33509353 = 33509420
97 + 33509323 = 33509420
151 + 33509269 = 33509420
163 + 33509257 = 33509420
211 + 33509209 = 33509420

Showing the first eight; more decompositions exist.
