Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631080, here are decompositions:

  • 43 + 8631037 = 8631080
  • 79 + 8631001 = 8631080
  • 97 + 8630983 = 8631080
  • 109 + 8630971 = 8631080
  • 151 + 8630929 = 8631080
  • 181 + 8630899 = 8631080
  • 223 + 8630857 = 8631080
  • 229 + 8630851 = 8631080

Showing the first eight; more decompositions exist.
