Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8016, here are decompositions:
- 5 + 8011 = 8016
- 7 + 8009 = 8016
- 23 + 7993 = 8016
- 53 + 7963 = 8016
- 67 + 7949 = 8016
- 79 + 7937 = 8016
- 83 + 7933 = 8016
- 89 + 7927 = 8016
Showing the first eight; more decompositions exist.
