Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635986, here are decompositions:

  • 5 + 8635981 = 8635986
  • 17 + 8635969 = 8635986
  • 19 + 8635967 = 8635986
  • 53 + 8635933 = 8635986
  • 59 + 8635927 = 8635986
  • 67 + 8635919 = 8635986
  • 89 + 8635897 = 8635986
  • 103 + 8635883 = 8635986

Showing the first eight; more decompositions exist.
