Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1268, here are decompositions:
- 19 + 1249 = 1268
- 31 + 1237 = 1268
- 37 + 1231 = 1268
- 67 + 1201 = 1268
- 97 + 1171 = 1268
- 139 + 1129 = 1268
- 151 + 1117 = 1268
- 181 + 1087 = 1268
Showing the first eight; more decompositions exist.
