Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10238, here are decompositions:
- 61 + 10177 = 10238
- 79 + 10159 = 10238
- 97 + 10141 = 10238
- 127 + 10111 = 10238
- 139 + 10099 = 10238
- 199 + 10039 = 10238
- 229 + 10009 = 10238
- 271 + 9967 = 10238
Showing the first eight; more decompositions exist.
