Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1764, here are decompositions:

  • 5 + 1759 = 1764
  • 11 + 1753 = 1764
  • 17 + 1747 = 1764
  • 23 + 1741 = 1764
  • 31 + 1733 = 1764
  • 41 + 1723 = 1764
  • 43 + 1721 = 1764
  • 67 + 1697 = 1764

Showing the first eight; more decompositions exist.
