Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1750, here are decompositions:

3 + 1747 = 1750
17 + 1733 = 1750
29 + 1721 = 1750
41 + 1709 = 1750
53 + 1697 = 1750
83 + 1667 = 1750
113 + 1637 = 1750
131 + 1619 = 1750

Showing the first eight; more decompositions exist.
