Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631370, here are decompositions:

  • 3 + 8631367 = 8631370
  • 29 + 8631341 = 8631370
  • 101 + 8631269 = 8631370
  • 179 + 8631191 = 8631370
  • 347 + 8631023 = 8631370
  • 353 + 8631017 = 8631370
  • 359 + 8631011 = 8631370
  • 467 + 8630903 = 8631370

Showing the first eight; more decompositions exist.
