Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687518, here are decompositions:

  • 5 + 8687513 = 8687518
  • 41 + 8687477 = 8687518
  • 89 + 8687429 = 8687518
  • 131 + 8687387 = 8687518
  • 137 + 8687381 = 8687518
  • 149 + 8687369 = 8687518
  • 197 + 8687321 = 8687518
  • 227 + 8687291 = 8687518

Showing the first eight; more decompositions exist.
