Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22198, here are decompositions:
- 5 + 22193 = 22198
- 41 + 22157 = 22198
- 89 + 22109 = 22198
- 107 + 22091 = 22198
- 131 + 22067 = 22198
- 167 + 22031 = 22198
- 269 + 21929 = 22198
- 317 + 21881 = 22198
Showing the first eight; more decompositions exist.
