Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22566, here are decompositions:
- 17 + 22549 = 22566
- 23 + 22543 = 22566
- 83 + 22483 = 22566
- 97 + 22469 = 22566
- 113 + 22453 = 22566
- 157 + 22409 = 22566
- 197 + 22369 = 22566
- 199 + 22367 = 22566
Showing the first eight; more decompositions exist.
