Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173712, here are decompositions:
- 5 + 173707 = 173712
- 13 + 173699 = 173712
- 29 + 173683 = 173712
- 41 + 173671 = 173712
- 43 + 173669 = 173712
- 53 + 173659 = 173712
- 61 + 173651 = 173712
- 83 + 173629 = 173712
Showing the first eight; more decompositions exist.
