Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709040, here are decompositions:

  • 71 + 8708969 = 8709040
  • 191 + 8708849 = 8709040
  • 233 + 8708807 = 8709040
  • 383 + 8708657 = 8709040
  • 401 + 8708639 = 8709040
  • 419 + 8708621 = 8709040
  • 449 + 8708591 = 8709040
  • 503 + 8708537 = 8709040

Showing the first eight; more decompositions exist.
