Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12256, here are decompositions:
- 3 + 12253 = 12256
- 5 + 12251 = 12256
- 17 + 12239 = 12256
- 29 + 12227 = 12256
- 53 + 12203 = 12256
- 59 + 12197 = 12256
- 107 + 12149 = 12256
- 113 + 12143 = 12256
Showing the first eight; more decompositions exist.
