Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16656, here are decompositions:
- 5 + 16651 = 16656
- 7 + 16649 = 16656
- 23 + 16633 = 16656
- 37 + 16619 = 16656
- 53 + 16603 = 16656
- 83 + 16573 = 16656
- 89 + 16567 = 16656
- 103 + 16553 = 16656
Showing the first eight; more decompositions exist.
