Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1446, here are decompositions:
- 7 + 1439 = 1446
- 13 + 1433 = 1446
- 17 + 1429 = 1446
- 19 + 1427 = 1446
- 23 + 1423 = 1446
- 37 + 1409 = 1446
- 47 + 1399 = 1446
- 73 + 1373 = 1446
Showing the first eight; more decompositions exist.
