Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533720, here are decompositions:

61 + 33533659 = 33533720
79 + 33533641 = 33533720
193 + 33533527 = 33533720
223 + 33533497 = 33533720
229 + 33533491 = 33533720
277 + 33533443 = 33533720
313 + 33533407 = 33533720
379 + 33533341 = 33533720

Showing the first eight; more decompositions exist.
