Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28500, here are decompositions:

  • 7 + 28493 = 28500
  • 23 + 28477 = 28500
  • 37 + 28463 = 28500
  • 53 + 28447 = 28500
  • 61 + 28439 = 28500
  • 67 + 28433 = 28500
  • 71 + 28429 = 28500
  • 89 + 28411 = 28500

Showing the first eight; more decompositions exist.
