Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1306, here are decompositions:
- 3 + 1303 = 1306
- 5 + 1301 = 1306
- 17 + 1289 = 1306
- 23 + 1283 = 1306
- 29 + 1277 = 1306
- 47 + 1259 = 1306
- 83 + 1223 = 1306
- 89 + 1217 = 1306
Showing the first eight; more decompositions exist.
