Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640712, here are decompositions:

  • 5 + 8640707 = 8640712
  • 11 + 8640701 = 8640712
  • 23 + 8640689 = 8640712
  • 29 + 8640683 = 8640712
  • 293 + 8640419 = 8640712
  • 383 + 8640329 = 8640712
  • 449 + 8640263 = 8640712
  • 461 + 8640251 = 8640712

Showing the first eight; more decompositions exist.
