Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33568220, here are decompositions:

13 + 33568207 = 33568220
31 + 33568189 = 33568220
43 + 33568177 = 33568220
61 + 33568159 = 33568220
67 + 33568153 = 33568220
97 + 33568123 = 33568220
151 + 33568069 = 33568220
337 + 33567883 = 33568220

Showing the first eight; more decompositions exist.
