Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11256, here are decompositions:
- 5 + 11251 = 11256
- 13 + 11243 = 11256
- 17 + 11239 = 11256
- 43 + 11213 = 11256
- 59 + 11197 = 11256
- 79 + 11177 = 11256
- 83 + 11173 = 11256
- 97 + 11159 = 11256
Showing the first eight; more decompositions exist.
