Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1276, here are decompositions:
- 17 + 1259 = 1276
- 47 + 1229 = 1276
- 53 + 1223 = 1276
- 59 + 1217 = 1276
- 83 + 1193 = 1276
- 89 + 1187 = 1276
- 113 + 1163 = 1276
- 167 + 1109 = 1276
Showing the first eight; more decompositions exist.
