Default I Think I Have A Primality test based on the Lehmer´s totient problem

Introduction: Lehmer´s totient problem is a mathematical assertion which states that there does not exist a composite positive integer x that satisfies the following:

Let f(x) be Euler´s phi function
Property that composite numbers do not satisfy:
f(x) divides x-1

If this conjecture was proved I could formulate a primality test based on Lehmer´s problem,the primality test would be as follows:

Let x be a positive integer

If f(x) divides x-1 return PRIME
If f(x) does not divide x-1 return COMPOSITE

Well this was what I wanted to share, thank you for reading
