Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631130, here are decompositions:

  • 47 + 8631083 = 8631130
  • 89 + 8631041 = 8631130
  • 107 + 8631023 = 8631130
  • 113 + 8631017 = 8631130
  • 227 + 8630903 = 8631130
  • 269 + 8630861 = 8631130
  • 293 + 8630837 = 8631130
  • 317 + 8630813 = 8631130

Showing the first eight; more decompositions exist.
