Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1756, here are decompositions:

3 + 1753 = 1756
23 + 1733 = 1756
47 + 1709 = 1756
59 + 1697 = 1756
89 + 1667 = 1756
137 + 1619 = 1756
149 + 1607 = 1756
173 + 1583 = 1756

Showing the first eight; more decompositions exist.
