Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620566, here are decompositions:

  • 13 + 8620553 = 8620566
  • 23 + 8620543 = 8620566
  • 37 + 8620529 = 8620566
  • 67 + 8620499 = 8620566
  • 137 + 8620429 = 8620566
  • 173 + 8620393 = 8620566
  • 197 + 8620369 = 8620566
  • 239 + 8620327 = 8620566

Showing the first eight; more decompositions exist.
