Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9664, here are decompositions:
- 3 + 9661 = 9664
- 41 + 9623 = 9664
- 113 + 9551 = 9664
- 131 + 9533 = 9664
- 167 + 9497 = 9664
- 173 + 9491 = 9664
- 191 + 9473 = 9664
- 197 + 9467 = 9664
Showing the first eight; more decompositions exist.
