Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28518, here are decompositions:

  • 5 + 28513 = 28518
  • 19 + 28499 = 28518
  • 41 + 28477 = 28518
  • 71 + 28447 = 28518
  • 79 + 28439 = 28518
  • 89 + 28429 = 28518
  • 107 + 28411 = 28518
  • 109 + 28409 = 28518

Showing the first eight; more decompositions exist.
