Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9642, here are decompositions:
- 11 + 9631 = 9642
- 13 + 9629 = 9642
- 19 + 9623 = 9642
- 23 + 9619 = 9642
- 29 + 9613 = 9642
- 41 + 9601 = 9642
- 103 + 9539 = 9642
- 109 + 9533 = 9642
Showing the first eight; more decompositions exist.
