Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15528, here are decompositions:

  • 17 + 15511 = 15528
  • 31 + 15497 = 15528
  • 61 + 15467 = 15528
  • 67 + 15461 = 15528
  • 89 + 15439 = 15528
  • 101 + 15427 = 15528
  • 127 + 15401 = 15528
  • 137 + 15391 = 15528

Showing the first eight; more decompositions exist.
