Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1308, here are decompositions:
- 5 + 1303 = 1308
- 7 + 1301 = 1308
- 11 + 1297 = 1308
- 17 + 1291 = 1308
- 19 + 1289 = 1308
- 29 + 1279 = 1308
- 31 + 1277 = 1308
- 59 + 1249 = 1308
Showing the first eight; more decompositions exist.
