Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717200, here are decompositions:

  • 29 + 8717171 = 8717200
  • 83 + 8717117 = 8717200
  • 179 + 8717021 = 8717200
  • 257 + 8716943 = 8717200
  • 281 + 8716919 = 8717200
  • 311 + 8716889 = 8717200
  • 347 + 8716853 = 8717200
  • 383 + 8716817 = 8717200

Showing the first eight; more decompositions exist.
