Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673720, here are decompositions:

  • 17 + 8673703 = 8673720
  • 37 + 8673683 = 8673720
  • 43 + 8673677 = 8673720
  • 109 + 8673611 = 8673720
  • 127 + 8673593 = 8673720
  • 149 + 8673571 = 8673720
  • 151 + 8673569 = 8673720
  • 173 + 8673547 = 8673720

Showing the first eight; more decompositions exist.
