Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21692, here are decompositions:
- 19 + 21673 = 21692
- 31 + 21661 = 21692
- 43 + 21649 = 21692
- 79 + 21613 = 21692
- 103 + 21589 = 21692
- 163 + 21529 = 21692
- 193 + 21499 = 21692
- 199 + 21493 = 21692
Showing the first eight; more decompositions exist.
