Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499690, here are decompositions:

41 + 33499649 = 33499690
47 + 33499643 = 33499690
53 + 33499637 = 33499690
71 + 33499619 = 33499690
89 + 33499601 = 33499690
113 + 33499577 = 33499690
281 + 33499409 = 33499690
317 + 33499373 = 33499690

Showing the first eight; more decompositions exist.
