Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610720, here are decompositions:

  • 61 + 8610659 = 8610720
  • 71 + 8610649 = 8610720
  • 103 + 8610617 = 8610720
  • 113 + 8610607 = 8610720
  • 137 + 8610583 = 8610720
  • 163 + 8610557 = 8610720
  • 197 + 8610523 = 8610720
  • 199 + 8610521 = 8610720

Showing the first eight; more decompositions exist.
