Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91666, here are decompositions:
- 83 + 91583 = 91666
- 89 + 91577 = 91666
- 137 + 91529 = 91666
- 167 + 91499 = 91666
- 173 + 91493 = 91666
- 233 + 91433 = 91666
- 269 + 91397 = 91666
- 293 + 91373 = 91666
Showing the first eight; more decompositions exist.
