Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715904, here are decompositions:

  • 3 + 8715901 = 8715904
  • 17 + 8715887 = 8715904
  • 23 + 8715881 = 8715904
  • 173 + 8715731 = 8715904
  • 233 + 8715671 = 8715904
  • 251 + 8715653 = 8715904
  • 257 + 8715647 = 8715904
  • 317 + 8715587 = 8715904

Showing the first eight; more decompositions exist.
