Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509556, here are decompositions:

29 + 33509527 = 33509556
127 + 33509429 = 33509556
139 + 33509417 = 33509556
163 + 33509393 = 33509556
167 + 33509389 = 33509556
229 + 33509327 = 33509556
233 + 33509323 = 33509556
277 + 33509279 = 33509556

Showing the first eight; more decompositions exist.
