Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86628, here are decompositions:

  • 29 + 86599 = 86628
  • 41 + 86587 = 86628
  • 67 + 86561 = 86628
  • 89 + 86539 = 86628
  • 97 + 86531 = 86628
  • 127 + 86501 = 86628
  • 137 + 86491 = 86628
  • 151 + 86477 = 86628

Showing the first eight; more decompositions exist.
