Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1316, here are decompositions:
- 13 + 1303 = 1316
- 19 + 1297 = 1316
- 37 + 1279 = 1316
- 67 + 1249 = 1316
- 79 + 1237 = 1316
- 103 + 1213 = 1316
- 163 + 1153 = 1316
- 193 + 1123 = 1316
Showing the first eight; more decompositions exist.
