Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23866, here are decompositions:
- 47 + 23819 = 23866
- 53 + 23813 = 23866
- 113 + 23753 = 23866
- 179 + 23687 = 23866
- 197 + 23669 = 23866
- 233 + 23633 = 23866
- 239 + 23627 = 23866
- 257 + 23609 = 23866
Showing the first eight; more decompositions exist.
