Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17680, here are decompositions:
- 11 + 17669 = 17680
- 23 + 17657 = 17680
- 53 + 17627 = 17680
- 71 + 17609 = 17680
- 83 + 17597 = 17680
- 101 + 17579 = 17680
- 107 + 17573 = 17680
- 191 + 17489 = 17680
Showing the first eight; more decompositions exist.
