Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7782, here are decompositions:

  • 23 + 7759 = 7782
  • 29 + 7753 = 7782
  • 41 + 7741 = 7782
  • 59 + 7723 = 7782
  • 79 + 7703 = 7782
  • 83 + 7699 = 7782
  • 101 + 7681 = 7782
  • 109 + 7673 = 7782

Showing the first eight; more decompositions exist.
