Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10666, here are decompositions:
- 3 + 10663 = 10666
- 53 + 10613 = 10666
- 59 + 10607 = 10666
- 107 + 10559 = 10666
- 137 + 10529 = 10666
- 167 + 10499 = 10666
- 179 + 10487 = 10666
- 233 + 10433 = 10666
Showing the first eight; more decompositions exist.
