Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656542, here are decompositions:

  • 5 + 8656537 = 8656542
  • 19 + 8656523 = 8656542
  • 31 + 8656511 = 8656542
  • 43 + 8656499 = 8656542
  • 61 + 8656481 = 8656542
  • 73 + 8656469 = 8656542
  • 79 + 8656463 = 8656542
  • 109 + 8656433 = 8656542

Showing the first eight; more decompositions exist.
