Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10500, here are decompositions:

  • 13 + 10487 = 10500
  • 23 + 10477 = 10500
  • 37 + 10463 = 10500
  • 41 + 10459 = 10500
  • 43 + 10457 = 10500
  • 47 + 10453 = 10500
  • 67 + 10433 = 10500
  • 71 + 10429 = 10500

Showing the first eight; more decompositions exist.
