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.
