Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687198, here are decompositions:

  • 67 + 8687131 = 8687198
  • 109 + 8687089 = 8687198
  • 199 + 8686999 = 8687198
  • 547 + 8686651 = 8687198
  • 631 + 8686567 = 8687198
  • 727 + 8686471 = 8687198
  • 739 + 8686459 = 8687198
  • 829 + 8686369 = 8687198

Showing the first eight; more decompositions exist.
