Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515440, here are decompositions:

3 + 33515437 = 33515440
71 + 33515369 = 33515440
83 + 33515357 = 33515440
107 + 33515333 = 33515440
173 + 33515267 = 33515440
197 + 33515243 = 33515440
281 + 33515159 = 33515440
311 + 33515129 = 33515440

Showing the first eight; more decompositions exist.
