Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636138, here are decompositions:

  • 31 + 8636107 = 8636138
  • 139 + 8635999 = 8636138
  • 157 + 8635981 = 8636138
  • 211 + 8635927 = 8636138
  • 241 + 8635897 = 8636138
  • 271 + 8635867 = 8636138
  • 409 + 8635729 = 8636138
  • 421 + 8635717 = 8636138

Showing the first eight; more decompositions exist.
