Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1758, here are decompositions:
- 5 + 1753 = 1758
- 11 + 1747 = 1758
- 17 + 1741 = 1758
- 37 + 1721 = 1758
- 59 + 1699 = 1758
- 61 + 1697 = 1758
- 89 + 1669 = 1758
- 101 + 1657 = 1758
Showing the first eight; more decompositions exist.
