Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1344, here are decompositions:
- 17 + 1327 = 1344
- 23 + 1321 = 1344
- 37 + 1307 = 1344
- 41 + 1303 = 1344
- 43 + 1301 = 1344
- 47 + 1297 = 1344
- 53 + 1291 = 1344
- 61 + 1283 = 1344
Showing the first eight; more decompositions exist.
