Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13500, here are decompositions:

  • 13 + 13487 = 13500
  • 23 + 13477 = 13500
  • 31 + 13469 = 13500
  • 37 + 13463 = 13500
  • 43 + 13457 = 13500
  • 59 + 13441 = 13500
  • 79 + 13421 = 13500
  • 83 + 13417 = 13500

Showing the first eight; more decompositions exist.
