Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550664, here are decompositions:

3 + 33550661 = 33550664
31 + 33550633 = 33550664
73 + 33550591 = 33550664
97 + 33550567 = 33550664
151 + 33550513 = 33550664
163 + 33550501 = 33550664
223 + 33550441 = 33550664
271 + 33550393 = 33550664

Showing the first eight; more decompositions exist.
