Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10656, here are decompositions:
- 5 + 10651 = 10656
- 17 + 10639 = 10656
- 29 + 10627 = 10656
- 43 + 10613 = 10656
- 59 + 10597 = 10656
- 67 + 10589 = 10656
- 89 + 10567 = 10656
- 97 + 10559 = 10656
Showing the first eight; more decompositions exist.
