Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68198, here are decompositions:
- 37 + 68161 = 68198
- 127 + 68071 = 68198
- 139 + 68059 = 68198
- 157 + 68041 = 68198
- 211 + 67987 = 68198
- 241 + 67957 = 68198
- 271 + 67927 = 68198
- 307 + 67891 = 68198
Showing the first eight; more decompositions exist.
