Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1682, here are decompositions:
- 13 + 1669 = 1682
- 19 + 1663 = 1682
- 61 + 1621 = 1682
- 73 + 1609 = 1682
- 103 + 1579 = 1682
- 139 + 1543 = 1682
- 151 + 1531 = 1682
- 193 + 1489 = 1682
Showing the first eight; more decompositions exist.
