Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 776, here are decompositions:

  • 3 + 773 = 776
  • 7 + 769 = 776
  • 19 + 757 = 776
  • 37 + 739 = 776
  • 43 + 733 = 776
  • 67 + 709 = 776
  • 103 + 673 = 776
  • 157 + 619 = 776

Showing the first eight; more decompositions exist.
