Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12266, here are decompositions:
- 3 + 12263 = 12266
- 13 + 12253 = 12266
- 103 + 12163 = 12266
- 109 + 12157 = 12266
- 157 + 12109 = 12266
- 193 + 12073 = 12266
- 223 + 12043 = 12266
- 229 + 12037 = 12266
Showing the first eight; more decompositions exist.
