Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22666, here are decompositions:
- 23 + 22643 = 22666
- 29 + 22637 = 22666
- 47 + 22619 = 22666
- 53 + 22613 = 22666
- 197 + 22469 = 22666
- 233 + 22433 = 22666
- 257 + 22409 = 22666
- 269 + 22397 = 22666
Showing the first eight; more decompositions exist.
