Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106680, here are decompositions:
- 11 + 106669 = 106680
- 17 + 106663 = 106680
- 19 + 106661 = 106680
- 23 + 106657 = 106680
- 31 + 106649 = 106680
- 43 + 106637 = 106680
- 53 + 106627 = 106680
- 59 + 106621 = 106680
Showing the first eight; more decompositions exist.
