Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727864, here are decompositions:

  • 7 + 8727857 = 8727864
  • 73 + 8727791 = 8727864
  • 97 + 8727767 = 8727864
  • 107 + 8727757 = 8727864
  • 137 + 8727727 = 8727864
  • 163 + 8727701 = 8727864
  • 191 + 8727673 = 8727864
  • 241 + 8727623 = 8727864

Showing the first eight; more decompositions exist.
