Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91660, here are decompositions:
- 29 + 91631 = 91660
- 83 + 91577 = 91660
- 89 + 91571 = 91660
- 131 + 91529 = 91660
- 167 + 91493 = 91660
- 197 + 91463 = 91660
- 227 + 91433 = 91660
- 263 + 91397 = 91660
Showing the first eight; more decompositions exist.
