Prime factorization can be determined by adding factor pairs together

Factor pairs are irrelevant in finding prime factorization

You can use factor pairs to find the prime factorization of a number by continuously dividing the number by its smallest prime factors until only prime numbers are left.

Factor pairs are only used for composite numbers, not prime numbers
