Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22768, here are decompositions:
- 17 + 22751 = 22768
- 29 + 22739 = 22768
- 41 + 22727 = 22768
- 47 + 22721 = 22768
- 59 + 22709 = 22768
- 71 + 22697 = 22768
- 89 + 22679 = 22768
- 131 + 22637 = 22768
Showing the first eight; more decompositions exist.
