Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509818, here are decompositions:

5 + 33509813 = 33509818
137 + 33509681 = 33509818
257 + 33509561 = 33509818
317 + 33509501 = 33509818
389 + 33509429 = 33509818
401 + 33509417 = 33509818
491 + 33509327 = 33509818
599 + 33509219 = 33509818

Showing the first eight; more decompositions exist.
