Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33568740, here are decompositions:

17 + 33568723 = 33568740
19 + 33568721 = 33568740
61 + 33568679 = 33568740
67 + 33568673 = 33568740
89 + 33568651 = 33568740
97 + 33568643 = 33568740
151 + 33568589 = 33568740
193 + 33568547 = 33568740

Showing the first eight; more decompositions exist.
