Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136542, here are decompositions:

  • 5 + 136537 = 136542
  • 11 + 136531 = 136542
  • 19 + 136523 = 136542
  • 23 + 136519 = 136542
  • 31 + 136511 = 136542
  • 41 + 136501 = 136542
  • 59 + 136483 = 136542
  • 61 + 136481 = 136542

Showing the first eight; more decompositions exist.
