Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636428, here are decompositions:

  • 5 + 8636423 = 8636428
  • 41 + 8636387 = 8636428
  • 167 + 8636261 = 8636428
  • 191 + 8636237 = 8636428
  • 347 + 8636081 = 8636428
  • 389 + 8636039 = 8636428
  • 461 + 8635967 = 8636428
  • 509 + 8635919 = 8636428

Showing the first eight; more decompositions exist.
