Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33501720, here are decompositions:

11 + 33501709 = 33501720
13 + 33501707 = 33501720
23 + 33501697 = 33501720
29 + 33501691 = 33501720
47 + 33501673 = 33501720
53 + 33501667 = 33501720
61 + 33501659 = 33501720
67 + 33501653 = 33501720

Showing the first eight; more decompositions exist.
