Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687478, here are decompositions:

  • 11 + 8687467 = 8687478
  • 17 + 8687461 = 8687478
  • 97 + 8687381 = 8687478
  • 109 + 8687369 = 8687478
  • 157 + 8687321 = 8687478
  • 179 + 8687299 = 8687478
  • 229 + 8687249 = 8687478
  • 251 + 8687227 = 8687478

Showing the first eight; more decompositions exist.
