Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509440, here are decompositions:

11 + 33509429 = 33509440
23 + 33509417 = 33509440
47 + 33509393 = 33509440
113 + 33509327 = 33509440
149 + 33509291 = 33509440
197 + 33509243 = 33509440
311 + 33509129 = 33509440
401 + 33509039 = 33509440

Showing the first eight; more decompositions exist.
