Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515280, here are decompositions:

13 + 33515267 = 33515280
23 + 33515257 = 33515280
37 + 33515243 = 33515280
47 + 33515233 = 33515280
151 + 33515129 = 33515280
181 + 33515099 = 33515280
193 + 33515087 = 33515280
223 + 33515057 = 33515280

Showing the first eight; more decompositions exist.
