Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640964, here are decompositions:

  • 53 + 8640911 = 8640964
  • 197 + 8640767 = 8640964
  • 251 + 8640713 = 8640964
  • 257 + 8640707 = 8640964
  • 263 + 8640701 = 8640964
  • 281 + 8640683 = 8640964
  • 461 + 8640503 = 8640964
  • 557 + 8640407 = 8640964

Showing the first eight; more decompositions exist.
