Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16166, here are decompositions:
- 79 + 16087 = 16166
- 97 + 16069 = 16166
- 103 + 16063 = 16166
- 109 + 16057 = 16166
- 193 + 15973 = 16166
- 229 + 15937 = 16166
- 277 + 15889 = 16166
- 307 + 15859 = 16166
Showing the first eight; more decompositions exist.
