Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533680, here are decompositions:

17 + 33533663 = 33533680
137 + 33533543 = 33533680
227 + 33533453 = 33533680
233 + 33533447 = 33533680
293 + 33533387 = 33533680
311 + 33533369 = 33533680
359 + 33533321 = 33533680
419 + 33533261 = 33533680

Showing the first eight; more decompositions exist.
