Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8192, here are decompositions:
- 13 + 8179 = 8192
- 31 + 8161 = 8192
- 103 + 8089 = 8192
- 139 + 8053 = 8192
- 181 + 8011 = 8192
- 199 + 7993 = 8192
- 229 + 7963 = 8192
- 241 + 7951 = 8192
Showing the first eight; more decompositions exist.
