Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22102, here are decompositions:
- 11 + 22091 = 22102
- 23 + 22079 = 22102
- 29 + 22073 = 22102
- 71 + 22031 = 22102
- 89 + 22013 = 22102
- 173 + 21929 = 22102
- 191 + 21911 = 22102
- 239 + 21863 = 22102
Showing the first eight; more decompositions exist.
