Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700856, here are decompositions:

  • 23 + 8700833 = 8700856
  • 29 + 8700827 = 8700856
  • 83 + 8700773 = 8700856
  • 89 + 8700767 = 8700856
  • 257 + 8700599 = 8700856
  • 293 + 8700563 = 8700856
  • 317 + 8700539 = 8700856
  • 383 + 8700473 = 8700856

Showing the first eight; more decompositions exist.
