Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12340, here are decompositions:
- 11 + 12329 = 12340
- 17 + 12323 = 12340
- 59 + 12281 = 12340
- 71 + 12269 = 12340
- 89 + 12251 = 12340
- 101 + 12239 = 12340
- 113 + 12227 = 12340
- 137 + 12203 = 12340
Showing the first eight; more decompositions exist.
