Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505388, here are decompositions:

79 + 33505309 = 33505388
127 + 33505261 = 33505388
211 + 33505177 = 33505388
271 + 33505117 = 33505388
331 + 33505057 = 33505388
337 + 33505051 = 33505388
349 + 33505039 = 33505388
379 + 33505009 = 33505388

Showing the first eight; more decompositions exist.
