Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606640, here are decompositions:

17 + 33606623 = 33606640
59 + 33606581 = 33606640
113 + 33606527 = 33606640
131 + 33606509 = 33606640
227 + 33606413 = 33606640
233 + 33606407 = 33606640
239 + 33606401 = 33606640
269 + 33606371 = 33606640

Showing the first eight; more decompositions exist.
