Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700864, here are decompositions:

  • 31 + 8700833 = 8700864
  • 37 + 8700827 = 8700864
  • 47 + 8700817 = 8700864
  • 71 + 8700793 = 8700864
  • 97 + 8700767 = 8700864
  • 113 + 8700751 = 8700864
  • 167 + 8700697 = 8700864
  • 283 + 8700581 = 8700864

Showing the first eight; more decompositions exist.
