Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67666, here are decompositions:
- 47 + 67619 = 67666
- 59 + 67607 = 67666
- 89 + 67577 = 67666
- 107 + 67559 = 67666
- 167 + 67499 = 67666
- 173 + 67493 = 67666
- 233 + 67433 = 67666
- 239 + 67427 = 67666
Showing the first eight; more decompositions exist.
