Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64768, here are decompositions:
- 5 + 64763 = 64768
- 59 + 64709 = 64768
- 89 + 64679 = 64768
- 101 + 64667 = 64768
- 107 + 64661 = 64768
- 167 + 64601 = 64768
- 191 + 64577 = 64768
- 269 + 64499 = 64768
Showing the first eight; more decompositions exist.
