Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1444, here are decompositions:
- 5 + 1439 = 1444
- 11 + 1433 = 1444
- 17 + 1427 = 1444
- 71 + 1373 = 1444
- 83 + 1361 = 1444
- 137 + 1307 = 1444
- 167 + 1277 = 1444
- 227 + 1217 = 1444
Showing the first eight; more decompositions exist.
