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.
