Solve Goldbach's Conjecture
  • [Goldbach's Conjecture](https://en.wikipedia.org/wiki/Goldbach%27s_conjecture) states that every even whole number greater than 2 is the sum of 2 prime numbers. Your task is to return those 2 prime numbers, given an even whole number as input. There are often multiple solutions - any solution will do.
  • # Input/Output Examples
  • These examples only show one of potentially many possible outputs.
  • ```
  • 4 -> 2, 2
  • 6 -> 3, 3
  • 24 -> 5, 19
  • 120 -> 7, 113
  • 1000 -> 3, 997
  • ```
  • This is code golf, so shortest answer in each language wins.
  • P.S. If no one finds a test case that has no solution, I'll consider the problem solved by engineer's induction.
