Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10660, here are decompositions:
- 3 + 10657 = 10660
- 29 + 10631 = 10660
- 47 + 10613 = 10660
- 53 + 10607 = 10660
- 59 + 10601 = 10660
- 71 + 10589 = 10660
- 101 + 10559 = 10660
- 131 + 10529 = 10660
Showing the first eight; more decompositions exist.
