Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628, here are decompositions:

  • 5 + 8623 = 8628
  • 19 + 8609 = 8628
  • 29 + 8599 = 8628
  • 31 + 8597 = 8628
  • 47 + 8581 = 8628
  • 89 + 8539 = 8628
  • 101 + 8527 = 8628
  • 107 + 8521 = 8628

Showing the first eight; more decompositions exist.
