Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533440, here are decompositions:

47 + 33533393 = 33533440
53 + 33533387 = 33533440
71 + 33533369 = 33533440
173 + 33533267 = 33533440
179 + 33533261 = 33533440
197 + 33533243 = 33533440
257 + 33533183 = 33533440
419 + 33533021 = 33533440

Showing the first eight; more decompositions exist.
