Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687848, here are decompositions:

  • 89 + 8687759 = 8687848
  • 149 + 8687699 = 8687848
  • 179 + 8687669 = 8687848
  • 419 + 8687429 = 8687848
  • 461 + 8687387 = 8687848
  • 467 + 8687381 = 8687848
  • 479 + 8687369 = 8687848
  • 557 + 8687291 = 8687848

Showing the first eight; more decompositions exist.
