Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1256, here are decompositions:
- 7 + 1249 = 1256
- 19 + 1237 = 1256
- 43 + 1213 = 1256
- 103 + 1153 = 1256
- 127 + 1129 = 1256
- 139 + 1117 = 1256
- 163 + 1093 = 1256
- 193 + 1063 = 1256
Showing the first eight; more decompositions exist.
