Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13656, here are decompositions:
- 7 + 13649 = 13656
- 23 + 13633 = 13656
- 29 + 13627 = 13656
- 37 + 13619 = 13656
- 43 + 13613 = 13656
- 59 + 13597 = 13656
- 79 + 13577 = 13656
- 89 + 13567 = 13656
Showing the first eight; more decompositions exist.
