Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33600640, here are decompositions:

113 + 33600527 = 33600640
137 + 33600503 = 33600640
251 + 33600389 = 33600640
257 + 33600383 = 33600640
401 + 33600239 = 33600640
461 + 33600179 = 33600640
503 + 33600137 = 33600640
509 + 33600131 = 33600640

Showing the first eight; more decompositions exist.
