Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47628, here are decompositions:

  • 5 + 47623 = 47628
  • 19 + 47609 = 47628
  • 29 + 47599 = 47628
  • 37 + 47591 = 47628
  • 47 + 47581 = 47628
  • 59 + 47569 = 47628
  • 101 + 47527 = 47628
  • 107 + 47521 = 47628

Showing the first eight; more decompositions exist.
