Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9678, here are decompositions:
- 17 + 9661 = 9678
- 29 + 9649 = 9678
- 47 + 9631 = 9678
- 59 + 9619 = 9678
- 127 + 9551 = 9678
- 131 + 9547 = 9678
- 139 + 9539 = 9678
- 157 + 9521 = 9678
Showing the first eight; more decompositions exist.
