Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715900, here are decompositions:

  • 13 + 8715887 = 8715900
  • 19 + 8715881 = 8715900
  • 23 + 8715877 = 8715900
  • 59 + 8715841 = 8715900
  • 107 + 8715793 = 8715900
  • 113 + 8715787 = 8715900
  • 131 + 8715769 = 8715900
  • 139 + 8715761 = 8715900

Showing the first eight; more decompositions exist.
