Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12682, here are decompositions:
- 11 + 12671 = 12682
- 23 + 12659 = 12682
- 29 + 12653 = 12682
- 41 + 12641 = 12682
- 71 + 12611 = 12682
- 113 + 12569 = 12682
- 179 + 12503 = 12682
- 191 + 12491 = 12682
Showing the first eight; more decompositions exist.
