Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18104, here are decompositions:
- 7 + 18097 = 18104
- 43 + 18061 = 18104
- 61 + 18043 = 18104
- 127 + 17977 = 18104
- 181 + 17923 = 18104
- 193 + 17911 = 18104
- 223 + 17881 = 18104
- 241 + 17863 = 18104
Showing the first eight; more decompositions exist.
