Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12472, here are decompositions:
- 59 + 12413 = 12472
- 71 + 12401 = 12472
- 149 + 12323 = 12472
- 191 + 12281 = 12472
- 233 + 12239 = 12472
- 269 + 12203 = 12472
- 311 + 12161 = 12472
- 353 + 12119 = 12472
Showing the first eight; more decompositions exist.
