Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17664, here are decompositions:
- 5 + 17659 = 17664
- 7 + 17657 = 17664
- 37 + 17627 = 17664
- 41 + 17623 = 17664
- 67 + 17597 = 17664
- 83 + 17581 = 17664
- 113 + 17551 = 17664
- 167 + 17497 = 17664
Showing the first eight; more decompositions exist.
