Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638196, here are decompositions:

  • 13 + 8638183 = 8638196
  • 79 + 8638117 = 8638196
  • 157 + 8638039 = 8638196
  • 163 + 8638033 = 8638196
  • 223 + 8637973 = 8638196
  • 349 + 8637847 = 8638196
  • 367 + 8637829 = 8638196
  • 409 + 8637787 = 8638196

Showing the first eight; more decompositions exist.
