Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 196, here are decompositions:
- 3 + 193 = 196
- 5 + 191 = 196
- 17 + 179 = 196
- 23 + 173 = 196
- 29 + 167 = 196
- 47 + 149 = 196
- 59 + 137 = 196
- 83 + 113 = 196
Showing the first eight; more decompositions exist.
