Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8256, here are decompositions:
- 13 + 8243 = 8256
- 19 + 8237 = 8256
- 23 + 8233 = 8256
- 37 + 8219 = 8256
- 47 + 8209 = 8256
- 89 + 8167 = 8256
- 109 + 8147 = 8256
- 139 + 8117 = 8256
Showing the first eight; more decompositions exist.
