Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720814, here are decompositions:

  • 5 + 8720809 = 8720814
  • 7 + 8720807 = 8720814
  • 17 + 8720797 = 8720814
  • 31 + 8720783 = 8720814
  • 41 + 8720773 = 8720814
  • 43 + 8720771 = 8720814
  • 101 + 8720713 = 8720814
  • 107 + 8720707 = 8720814

Showing the first eight; more decompositions exist.
