Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631636, here are decompositions:

  • 7 + 8631629 = 8631636
  • 19 + 8631617 = 8631636
  • 37 + 8631599 = 8631636
  • 67 + 8631569 = 8631636
  • 103 + 8631533 = 8631636
  • 137 + 8631499 = 8631636
  • 157 + 8631479 = 8631636
  • 257 + 8631379 = 8631636

Showing the first eight; more decompositions exist.
