Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9722, here are decompositions:
- 3 + 9719 = 9722
- 43 + 9679 = 9722
- 61 + 9661 = 9722
- 73 + 9649 = 9722
- 79 + 9643 = 9722
- 103 + 9619 = 9722
- 109 + 9613 = 9722
- 211 + 9511 = 9722
Showing the first eight; more decompositions exist.
