Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 682, here are decompositions:
- 5 + 677 = 682
- 23 + 659 = 682
- 29 + 653 = 682
- 41 + 641 = 682
- 83 + 599 = 682
- 89 + 593 = 682
- 113 + 569 = 682
- 173 + 509 = 682
Showing the first eight; more decompositions exist.
