Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509008, here are decompositions:

89 + 33508919 = 33509008
107 + 33508901 = 33509008
149 + 33508859 = 33509008
179 + 33508829 = 33509008
191 + 33508817 = 33509008
227 + 33508781 = 33509008
347 + 33508661 = 33509008
389 + 33508619 = 33509008

Showing the first eight; more decompositions exist.
