Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631450, here are decompositions:

  • 59 + 8631391 = 8631450
  • 71 + 8631379 = 8631450
  • 83 + 8631367 = 8631450
  • 109 + 8631341 = 8631450
  • 131 + 8631319 = 8631450
  • 167 + 8631283 = 8631450
  • 173 + 8631277 = 8631450
  • 181 + 8631269 = 8631450

Showing the first eight; more decompositions exist.
