Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513788, here are decompositions:

127 + 33513661 = 33513788
157 + 33513631 = 33513788
229 + 33513559 = 33513788
241 + 33513547 = 33513788
331 + 33513457 = 33513788
349 + 33513439 = 33513788
367 + 33513421 = 33513788
421 + 33513367 = 33513788

Showing the first eight; more decompositions exist.
