Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13268, here are decompositions:
- 19 + 13249 = 13268
- 97 + 13171 = 13268
- 109 + 13159 = 13268
- 349 + 12919 = 13268
- 379 + 12889 = 13268
- 439 + 12829 = 13268
- 487 + 12781 = 13268
- 547 + 12721 = 13268
Showing the first eight; more decompositions exist.
