Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87682, here are decompositions:
- 3 + 87679 = 87682
- 11 + 87671 = 87682
- 41 + 87641 = 87682
- 53 + 87629 = 87682
- 59 + 87623 = 87682
- 173 + 87509 = 87682
- 191 + 87491 = 87682
- 239 + 87443 = 87682
Showing the first eight; more decompositions exist.
