Reducing fractions the wrong way

In this code-golf challenge you have to find fractions that can be reduced the wrong way but still end up in the same number.

Example:

64/16 = 64/16=4/1 = 4

Of course you cannot just strike both 6es but here you still end up with the correct value. In this challenge you have to find examples like this.

###Details You have to write a function/program that accepts one positive integer n as input and outputs/returns a list/array of the fractions in format
numerator1,denominator1,numerator2,denominator2,...

The program has to find out for each fraction a/b with a+b=n whether it can be reduced the wrong way.

A fraction can be reduced the wrong way if and only if you can the same sequence of digits appears in a and b and if the value of the fraction stays the same if you remove the substring.

Example: 1536/353 can be 'reduced' to 16/3 but those two values are not equal so you cannot reduce this fraction the wrong way.

Note that this definition of reducing the wrong way can also include fractions that are reduced the right way: 110/10 = 11/1 is within the definition of reducing the wrong way even though it is a valid step.

Scoring

The least number of bytes wins. You can write a function or program that accepts an integer and returns an array or a program that uses stdin/stdout or you can consider n saved in a variable and in the end of the program the list must be saved in an other variable.
