Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13256, here are decompositions:
- 7 + 13249 = 13256
- 37 + 13219 = 13256
- 73 + 13183 = 13256
- 79 + 13177 = 13256
- 97 + 13159 = 13256
- 109 + 13147 = 13256
- 157 + 13099 = 13256
- 163 + 13093 = 13256
Showing the first eight; more decompositions exist.
