Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648628, here are decompositions:

  • 71 + 8648557 = 8648628
  • 97 + 8648531 = 8648628
  • 127 + 8648501 = 8648628
  • 181 + 8648447 = 8648628
  • 239 + 8648389 = 8648628
  • 257 + 8648371 = 8648628
  • 281 + 8648347 = 8648628
  • 311 + 8648317 = 8648628

Showing the first eight; more decompositions exist.
