Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13486, here are decompositions:
- 17 + 13469 = 13486
- 23 + 13463 = 13486
- 29 + 13457 = 13486
- 89 + 13397 = 13486
- 149 + 13337 = 13486
- 173 + 13313 = 13486
- 227 + 13259 = 13486
- 257 + 13229 = 13486
Showing the first eight; more decompositions exist.
