Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22828, here are decompositions:
- 11 + 22817 = 22828
- 17 + 22811 = 22828
- 41 + 22787 = 22828
- 59 + 22769 = 22828
- 89 + 22739 = 22828
- 101 + 22727 = 22828
- 107 + 22721 = 22828
- 131 + 22697 = 22828
Showing the first eight; more decompositions exist.
