Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631200, here are decompositions:

  • 7 + 8631193 = 8631200
  • 103 + 8631097 = 8631200
  • 163 + 8631037 = 8631200
  • 199 + 8631001 = 8631200
  • 229 + 8630971 = 8631200
  • 271 + 8630929 = 8631200
  • 349 + 8630851 = 8631200
  • 367 + 8630833 = 8631200

Showing the first eight; more decompositions exist.
