Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109722, here are decompositions:
- 5 + 109717 = 109722
- 59 + 109663 = 109722
- 61 + 109661 = 109722
- 83 + 109639 = 109722
- 101 + 109621 = 109722
- 103 + 109619 = 109722
- 113 + 109609 = 109722
- 139 + 109583 = 109722
Showing the first eight; more decompositions exist.
