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.
