Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21796, here are decompositions:
- 23 + 21773 = 21796
- 29 + 21767 = 21796
- 59 + 21737 = 21796
- 83 + 21713 = 21796
- 113 + 21683 = 21796
- 149 + 21647 = 21796
- 179 + 21617 = 21796
- 197 + 21599 = 21796
Showing the first eight; more decompositions exist.
