Find the number x that satisfies these two properties:
- The digits of x add up to a number x where x equals y times the number you get when you reverse the digits of y.
- Reverse the digits of x and find the prime factors of the number you get. Then take the sum of the squares of these prime factors and halve it. Removing the digit 0 from the new number yields back x.
