Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18588, here are decompositions:

  • 5 + 18583 = 18588
  • 47 + 18541 = 18588
  • 67 + 18521 = 18588
  • 71 + 18517 = 18588
  • 107 + 18481 = 18588
  • 127 + 18461 = 18588
  • 131 + 18457 = 18588
  • 137 + 18451 = 18588

Showing the first eight; more decompositions exist.
