Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631012, here are decompositions:

  • 11 + 8631001 = 8631012
  • 29 + 8630983 = 8631012
  • 41 + 8630971 = 8631012
  • 83 + 8630929 = 8631012
  • 109 + 8630903 = 8631012
  • 113 + 8630899 = 8631012
  • 151 + 8630861 = 8631012
  • 179 + 8630833 = 8631012

Showing the first eight; more decompositions exist.
