Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709664, here are decompositions:

  • 11 + 8709653 = 8709664
  • 17 + 8709647 = 8709664
  • 53 + 8709611 = 8709664
  • 101 + 8709563 = 8709664
  • 137 + 8709527 = 8709664
  • 233 + 8709431 = 8709664
  • 281 + 8709383 = 8709664
  • 347 + 8709317 = 8709664

Showing the first eight; more decompositions exist.
