Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509000, here are decompositions:

13 + 33508987 = 33509000
97 + 33508903 = 33509000
103 + 33508897 = 33509000
193 + 33508807 = 33509000
199 + 33508801 = 33509000
271 + 33508729 = 33509000
373 + 33508627 = 33509000
661 + 33508339 = 33509000

Showing the first eight; more decompositions exist.
