Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631372, here are decompositions:

  • 5 + 8631367 = 8631372
  • 31 + 8631341 = 8631372
  • 41 + 8631331 = 8631372
  • 53 + 8631319 = 8631372
  • 89 + 8631283 = 8631372
  • 103 + 8631269 = 8631372
  • 173 + 8631199 = 8631372
  • 179 + 8631193 = 8631372

Showing the first eight; more decompositions exist.
