Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685040, here are decompositions:

  • 59 + 8684981 = 8685040
  • 101 + 8684939 = 8685040
  • 137 + 8684903 = 8685040
  • 167 + 8684873 = 8685040
  • 179 + 8684861 = 8685040
  • 251 + 8684789 = 8685040
  • 257 + 8684783 = 8685040
  • 269 + 8684771 = 8685040

Showing the first eight; more decompositions exist.
