Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12198, here are decompositions:
- 37 + 12161 = 12198
- 41 + 12157 = 12198
- 79 + 12119 = 12198
- 89 + 12109 = 12198
- 97 + 12101 = 12198
- 101 + 12097 = 12198
- 127 + 12071 = 12198
- 149 + 12049 = 12198
Showing the first eight; more decompositions exist.
