Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21096, here are decompositions:
- 7 + 21089 = 21096
- 29 + 21067 = 21096
- 37 + 21059 = 21096
- 73 + 21023 = 21096
- 79 + 21017 = 21096
- 83 + 21013 = 21096
- 113 + 20983 = 21096
- 137 + 20959 = 21096
Showing the first eight; more decompositions exist.
