Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12792, here are decompositions:

  • 11 + 12781 = 12792
  • 29 + 12763 = 12792
  • 53 + 12739 = 12792
  • 71 + 12721 = 12792
  • 79 + 12713 = 12792
  • 89 + 12703 = 12792
  • 103 + 12689 = 12792
  • 139 + 12653 = 12792

Showing the first eight; more decompositions exist.
