Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10256, here are decompositions:
- 3 + 10253 = 10256
- 13 + 10243 = 10256
- 79 + 10177 = 10256
- 97 + 10159 = 10256
- 157 + 10099 = 10256
- 163 + 10093 = 10256
- 283 + 9973 = 10256
- 307 + 9949 = 10256
Showing the first eight; more decompositions exist.
