Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33568840, here are decompositions:

29 + 33568811 = 33568840
47 + 33568793 = 33568840
59 + 33568781 = 33568840
89 + 33568751 = 33568840
167 + 33568673 = 33568840
197 + 33568643 = 33568840
233 + 33568607 = 33568840
251 + 33568589 = 33568840

Showing the first eight; more decompositions exist.
