Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33568720, here are decompositions:

41 + 33568679 = 33568720
47 + 33568673 = 33568720
113 + 33568607 = 33568720
131 + 33568589 = 33568720
167 + 33568553 = 33568720
173 + 33568547 = 33568720
233 + 33568487 = 33568720
281 + 33568439 = 33568720

Showing the first eight; more decompositions exist.
