Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670564, here are decompositions:

  • 5 + 8670559 = 8670564
  • 11 + 8670553 = 8670564
  • 13 + 8670551 = 8670564
  • 31 + 8670533 = 8670564
  • 41 + 8670523 = 8670564
  • 61 + 8670503 = 8670564
  • 73 + 8670491 = 8670564
  • 83 + 8670481 = 8670564

Showing the first eight; more decompositions exist.
