Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28766, here are decompositions:
- 7 + 28759 = 28766
- 13 + 28753 = 28766
- 37 + 28729 = 28766
- 43 + 28723 = 28766
- 79 + 28687 = 28766
- 97 + 28669 = 28766
- 103 + 28663 = 28766
- 109 + 28657 = 28766
Showing the first eight; more decompositions exist.
