Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649808, here are decompositions:

  • 5 + 8649803 = 8649808
  • 17 + 8649791 = 8649808
  • 47 + 8649761 = 8649808
  • 131 + 8649677 = 8649808
  • 137 + 8649671 = 8649808
  • 179 + 8649629 = 8649808
  • 197 + 8649611 = 8649808
  • 227 + 8649581 = 8649808

Showing the first eight; more decompositions exist.
