Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71722, here are decompositions:
- 3 + 71719 = 71722
- 11 + 71711 = 71722
- 23 + 71699 = 71722
- 29 + 71693 = 71722
- 59 + 71663 = 71722
- 89 + 71633 = 71722
- 173 + 71549 = 71722
- 239 + 71483 = 71722
Showing the first eight; more decompositions exist.
