Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13456, here are decompositions:
- 5 + 13451 = 13456
- 59 + 13397 = 13456
- 89 + 13367 = 13456
- 197 + 13259 = 13456
- 227 + 13229 = 13456
- 239 + 13217 = 13456
- 269 + 13187 = 13456
- 293 + 13163 = 13456
Showing the first eight; more decompositions exist.
