Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1776, here are decompositions:

17 + 1759 = 1776
23 + 1753 = 1776
29 + 1747 = 1776
43 + 1733 = 1776
53 + 1723 = 1776
67 + 1709 = 1776
79 + 1697 = 1776
83 + 1693 = 1776

Showing the first eight; more decompositions exist.
