Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169722, here are decompositions:
- 13 + 169709 = 169722
- 29 + 169693 = 169722
- 31 + 169691 = 169722
- 41 + 169681 = 169722
- 61 + 169661 = 169722
- 73 + 169649 = 169722
- 83 + 169639 = 169722
- 89 + 169633 = 169722
Showing the first eight; more decompositions exist.
