Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17686, here are decompositions:
- 3 + 17683 = 17686
- 5 + 17681 = 17686
- 17 + 17669 = 17686
- 29 + 17657 = 17686
- 59 + 17627 = 17686
- 89 + 17597 = 17686
- 107 + 17579 = 17686
- 113 + 17573 = 17686
Showing the first eight; more decompositions exist.
