Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9658, here are decompositions:
- 29 + 9629 = 9658
- 71 + 9587 = 9658
- 107 + 9551 = 9658
- 137 + 9521 = 9658
- 167 + 9491 = 9658
- 179 + 9479 = 9658
- 191 + 9467 = 9658
- 197 + 9461 = 9658
Showing the first eight; more decompositions exist.
