Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 192, here are decompositions:
- 11 + 181 = 192
- 13 + 179 = 192
- 19 + 173 = 192
- 29 + 163 = 192
- 41 + 151 = 192
- 43 + 149 = 192
- 53 + 139 = 192
- 61 + 131 = 192
Showing the first eight; more decompositions exist.
