Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508768, here are decompositions:

47 + 33508721 = 33508768
107 + 33508661 = 33508768
149 + 33508619 = 33508768
191 + 33508577 = 33508768
269 + 33508499 = 33508768
281 + 33508487 = 33508768
467 + 33508301 = 33508768
479 + 33508289 = 33508768

Showing the first eight; more decompositions exist.
