Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12268, here are decompositions:
- 5 + 12263 = 12268
- 17 + 12251 = 12268
- 29 + 12239 = 12268
- 41 + 12227 = 12268
- 71 + 12197 = 12268
- 107 + 12161 = 12268
- 149 + 12119 = 12268
- 167 + 12101 = 12268
Showing the first eight; more decompositions exist.
