Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13312, here are decompositions:
- 3 + 13309 = 13312
- 53 + 13259 = 13312
- 71 + 13241 = 13312
- 83 + 13229 = 13312
- 149 + 13163 = 13312
- 191 + 13121 = 13312
- 263 + 13049 = 13312
- 269 + 13043 = 13312
Showing the first eight; more decompositions exist.
