Some think it is an interesting challenge. Prime numbers of up to a few hundred digits have real practical applications, in cryptography. However, the largest prime numbers found are much, much greater than that.

Look up a list of prime numbers (a Google search for "prime numbers" or "list of prime numbers" should do); every number (greater than 1) that is NOT a prime number is composite.

Look for a table of prime numbers. All the odd numbers that are NOT on this list are composite numbers.

Any two numbers who are relatively prime will workSo look at 9 and 4. Neither is prime and their GCD is 1.You must need two numbers with NO other factors in common.

Prime numbers are only really used for 3 things. 1) Cryptography. Look up the algorithm "RSA" in cryptography. It is widely used and relies heavily on prime numbers. 2) Attempted alien communications. Prime numbers are one of the simplest demonstrations of intelligence, and can be understood regardless of language or culture. Thus, many signals sent out to aliens include prime numbers to demonstrate we are intelligent. 3) Mathematical conversations, jokes, and beauty. Many mathematicians find prime numbers to be beautiful, and enjoy discussing them. Any particular person is unlikely to knowingly manipulate prime numbers in their life.

Look up a table of prime numbers. All those numbers that are not prime, are composite - except 1, which is neither prime nor composite.

Scroll down to related links and look at "List of prime numbers - Wikipedia".

There are many cases of prime numbers with a difference of 8, for example (3, 11), and (101, 109). Look at a list of prime numbers, and you will quickly find more examples. If you mean, without other prime numbers in between, I believe the first such pair is (89, 97). I am pretty sure you will find more - just look at a table of prime numbers.

Yes. Just search Google for "list of prime numbers", and you'll get not only that, but much larger lists as well. You might also look at the Wikipedia article on "prime numbers"; this will give you links to lists of prime numbers.

Look at a list of prime numbers. Select the ones whose difference is 2.

Yes, 997 is a prime number.You can either work it out, or look it up in a list of prime numbers!For list of the first 1,000 prime numbers, see Related links below this box.

Look for a table of prime numbers. All the odd numbers that are NOT on this list are composite numbers.

Numbers never end. You can always continue to add another digit to a number and make it larger. Because this is the case, you can continue to look forward forever for prime numbers. The difference/distance between the numbers may grow, but prime numbers will continue to appear.

3 * 13 (both prime numbers)

I suggest you look up a table of prime numbers. Any integer treater than one that is not in the table of prime numbers is a composite number.
