Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12406, here are decompositions:
- 5 + 12401 = 12406
- 29 + 12377 = 12406
- 59 + 12347 = 12406
- 83 + 12323 = 12406
- 137 + 12269 = 12406
- 167 + 12239 = 12406
- 179 + 12227 = 12406
- 257 + 12149 = 12406
Showing the first eight; more decompositions exist.
