Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12822, here are decompositions:

  • 13 + 12809 = 12822
  • 23 + 12799 = 12822
  • 31 + 12791 = 12822
  • 41 + 12781 = 12822
  • 59 + 12763 = 12822
  • 79 + 12743 = 12822
  • 83 + 12739 = 12822
  • 101 + 12721 = 12822

Showing the first eight; more decompositions exist.
