Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13658, here are decompositions:
- 31 + 13627 = 13658
- 61 + 13597 = 13658
- 67 + 13591 = 13658
- 181 + 13477 = 13658
- 241 + 13417 = 13658
- 277 + 13381 = 13658
- 331 + 13327 = 13658
- 349 + 13309 = 13658
Showing the first eight; more decompositions exist.
