Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22312, here are decompositions:
- 5 + 22307 = 22312
- 29 + 22283 = 22312
- 41 + 22271 = 22312
- 53 + 22259 = 22312
- 83 + 22229 = 22312
- 179 + 22133 = 22312
- 233 + 22079 = 22312
- 239 + 22073 = 22312
Showing the first eight; more decompositions exist.
