Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23170, here are decompositions:
- 3 + 23167 = 23170
- 11 + 23159 = 23170
- 53 + 23117 = 23170
- 71 + 23099 = 23170
- 83 + 23087 = 23170
- 89 + 23081 = 23170
- 107 + 23063 = 23170
- 113 + 23057 = 23170
Showing the first eight; more decompositions exist.
