Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8040, here are decompositions:
- 23 + 8017 = 8040
- 29 + 8011 = 8040
- 31 + 8009 = 8040
- 47 + 7993 = 8040
- 89 + 7951 = 8040
- 103 + 7937 = 8040
- 107 + 7933 = 8040
- 113 + 7927 = 8040
Showing the first eight; more decompositions exist.
