Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33568780, here are decompositions:

29 + 33568751 = 33568780
59 + 33568721 = 33568780
101 + 33568679 = 33568780
107 + 33568673 = 33568780
137 + 33568643 = 33568780
173 + 33568607 = 33568780
191 + 33568589 = 33568780
227 + 33568553 = 33568780

Showing the first eight; more decompositions exist.
