Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23166, here are decompositions:
- 7 + 23159 = 23166
- 23 + 23143 = 23166
- 67 + 23099 = 23166
- 79 + 23087 = 23166
- 103 + 23063 = 23166
- 107 + 23059 = 23166
- 109 + 23057 = 23166
- 113 + 23053 = 23166
Showing the first eight; more decompositions exist.
