Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13172, here are decompositions:
- 13 + 13159 = 13172
- 73 + 13099 = 13172
- 79 + 13093 = 13172
- 109 + 13063 = 13172
- 139 + 13033 = 13172
- 163 + 13009 = 13172
- 193 + 12979 = 13172
- 199 + 12973 = 13172
Showing the first eight; more decompositions exist.
