What is the sum of two prime numbers that equal 44?
I assume you are asking the question "what two prime numbers sum to 44". There may be other pairs of prime numbers that sum to 44, but 37 and 7 are both primes and their sum = 44.
Does the sum of two prime numbers equal a prime number?
If one of the two numbers is 2, the sum of two prime numbers may sometimes be a prime number. Examples of this are 2 + 11 = 13, 2 + 521 = 523, 2 + 281 = 283. There are an infinite number of similar examples where the sum of 2 plus a prime is another prime. However if neither number is 2, then the sum of two prime numbers is always an even number greater than 2 and therefore composite.

What is a pair of numbers that their greatest common factor is 1?
Such numbers are said to be "relatively prime". They may be two different prime numbers (e.g., 17 and 3); or they may simply have no prime factors in common (e.g., 25 and 14 - their prime factors are 5 x 5, and 2 x 7).
Is it true or false that two composite numbers are relatively prime and explain?
Two composite numbers may or may not be relatively prime, depending on their factors. Relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
Is it possible for the sum or product of two prime numbers be a prime?
It is impossible for the product of two prime numbers to be prime. It is impossible for the sum of two prime numbers to be prime as long as one of the numbers isn't 2.
What is the prime factorization for two?
