Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20716, here are decompositions:
- 23 + 20693 = 20716
- 53 + 20663 = 20716
- 89 + 20627 = 20716
- 167 + 20549 = 20716
- 173 + 20543 = 20716
- 233 + 20483 = 20716
- 239 + 20477 = 20716
- 317 + 20399 = 20716
Showing the first eight; more decompositions exist.
