Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85638, here are decompositions:

  • 11 + 85627 = 85638
  • 17 + 85621 = 85638
  • 19 + 85619 = 85638
  • 31 + 85607 = 85638
  • 37 + 85601 = 85638
  • 41 + 85597 = 85638
  • 61 + 85577 = 85638
  • 67 + 85571 = 85638

Showing the first eight; more decompositions exist.
