Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619784, here are decompositions:

  • 11 + 8619773 = 8619784
  • 71 + 8619713 = 8619784
  • 101 + 8619683 = 8619784
  • 191 + 8619593 = 8619784
  • 197 + 8619587 = 8619784
  • 233 + 8619551 = 8619784
  • 293 + 8619491 = 8619784
  • 311 + 8619473 = 8619784

Showing the first eight; more decompositions exist.
