Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490828, here are decompositions:

11 + 33490817 = 33490828
47 + 33490781 = 33490828
191 + 33490637 = 33490828
281 + 33490547 = 33490828
419 + 33490409 = 33490828
431 + 33490397 = 33490828
467 + 33490361 = 33490828
491 + 33490337 = 33490828

Showing the first eight; more decompositions exist.
