Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2196, here are decompositions:
- 17 + 2179 = 2196
- 43 + 2153 = 2196
- 53 + 2143 = 2196
- 59 + 2137 = 2196
- 67 + 2129 = 2196
- 83 + 2113 = 2196
- 97 + 2099 = 2196
- 107 + 2089 = 2196
Showing the first eight; more decompositions exist.
