Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23128, here are decompositions:
- 11 + 23117 = 23128
- 29 + 23099 = 23128
- 41 + 23087 = 23128
- 47 + 23081 = 23128
- 71 + 23057 = 23128
- 89 + 23039 = 23128
- 101 + 23027 = 23128
- 107 + 23021 = 23128
Showing the first eight; more decompositions exist.
