Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8064, here are decompositions:
- 5 + 8059 = 8064
- 11 + 8053 = 8064
- 47 + 8017 = 8064
- 53 + 8011 = 8064
- 71 + 7993 = 8064
- 101 + 7963 = 8064
- 113 + 7951 = 8064
- 127 + 7937 = 8064
Showing the first eight; more decompositions exist.
