Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687636, here are decompositions:

  • 37 + 8687599 = 8687636
  • 157 + 8687479 = 8687636
  • 277 + 8687359 = 8687636
  • 337 + 8687299 = 8687636
  • 409 + 8687227 = 8687636
  • 439 + 8687197 = 8687636
  • 487 + 8687149 = 8687636
  • 547 + 8687089 = 8687636

Showing the first eight; more decompositions exist.
