Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1270, here are decompositions:
- 11 + 1259 = 1270
- 41 + 1229 = 1270
- 47 + 1223 = 1270
- 53 + 1217 = 1270
- 83 + 1187 = 1270
- 89 + 1181 = 1270
- 107 + 1163 = 1270
- 167 + 1103 = 1270
Showing the first eight; more decompositions exist.
