Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17566, here are decompositions:

47 + 17519 = 17566
83 + 17483 = 17566
89 + 17477 = 17566
149 + 17417 = 17566
173 + 17393 = 17566
179 + 17387 = 17566
233 + 17333 = 17566
239 + 17327 = 17566

Showing the first eight; more decompositions exist.
