Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8222, here are decompositions:
- 3 + 8219 = 8222
- 13 + 8209 = 8222
- 31 + 8191 = 8222
- 43 + 8179 = 8222
- 61 + 8161 = 8222
- 163 + 8059 = 8222
- 211 + 8011 = 8222
- 229 + 7993 = 8222
Showing the first eight; more decompositions exist.
