Are all composite numbers made up of two prime numbers?

Total number refers to
① The greatest common divisor between two numbers is only the product of the two numbers of 1;
② The common divisor between two numbers is not only 1. If you multiply one of the divisors by the smallest number, you can divide it. The number multiplied is the composite number
Composite number, also known as composite number, is a positive integer satisfying any of the following (equivalent) conditions:
1. Is the product of two integers greater than 1;
2. Have a factor greater than 1 but less than itself;
3. Have at least three factors (factors);
4. It is neither 1 nor prime;
5. Non prime numbers with at least one prime factor
6. The product of two or more primes can form a composite number, and only one composite number. On the contrary, a composite number can be divided into the product of a group of primes, and can only be divided into the product of a group of primes. That is to say, the composite number composed of the product of more than three primes can not be regarded as the product of two primes!
From point 6, yes

The sum of prime and composite numbers is 15. The product is 36. What are the two numbers
