Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4256, here are decompositions:
- 3 + 4253 = 4256
- 13 + 4243 = 4256
- 37 + 4219 = 4256
- 79 + 4177 = 4256
- 97 + 4159 = 4256
- 103 + 4153 = 4256
- 127 + 4129 = 4256
- 157 + 4099 = 4256
Showing the first eight; more decompositions exist.
