Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15588, here are decompositions:

  • 5 + 15583 = 15588
  • 7 + 15581 = 15588
  • 19 + 15569 = 15588
  • 29 + 15559 = 15588
  • 37 + 15551 = 15588
  • 47 + 15541 = 15588
  • 61 + 15527 = 15588
  • 127 + 15461 = 15588

Showing the first eight; more decompositions exist.
