Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621884, here are decompositions:

  • 17 + 8621867 = 8621884
  • 23 + 8621861 = 8621884
  • 41 + 8621843 = 8621884
  • 53 + 8621831 = 8621884
  • 137 + 8621747 = 8621884
  • 191 + 8621693 = 8621884
  • 431 + 8621453 = 8621884
  • 641 + 8621243 = 8621884

Showing the first eight; more decompositions exist.
