Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550668, here are decompositions:

5 + 33550663 = 33550668
7 + 33550661 = 33550668
37 + 33550631 = 33550668
61 + 33550607 = 33550668
101 + 33550567 = 33550668
157 + 33550511 = 33550668
167 + 33550501 = 33550668
227 + 33550441 = 33550668

Showing the first eight; more decompositions exist.
