Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600720, here are decompositions:

  • 3 + 8600717 = 8600720
  • 19 + 8600701 = 8600720
  • 43 + 8600677 = 8600720
  • 127 + 8600593 = 8600720
  • 211 + 8600509 = 8600720
  • 223 + 8600497 = 8600720
  • 229 + 8600491 = 8600720
  • 283 + 8600437 = 8600720

Showing the first eight; more decompositions exist.
