Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533668, here are decompositions:

5 + 33533663 = 33533668
281 + 33533387 = 33533668
347 + 33533321 = 33533668
401 + 33533267 = 33533668
647 + 33533021 = 33533668
761 + 33532907 = 33533668
797 + 33532871 = 33533668
911 + 33532757 = 33533668

Showing the first eight; more decompositions exist.
