Well, honey, the Prime number pairs that differ by 5 are (3, 8), (11, 16), (17, 22), (41, 46), and so on. As long as one of the numbers in the pair is a prime number, and the other is that prime number plus or minus 5, you've got yourself a match. Math can be sassy like that!
Prime number pairs that differ by 5 are known as twin primes. The only twin prime pair that differs by 5 is (3, 5). In this pair, 3 and 5 are both prime numbers, and their difference is 5. Twin primes are a special case of prime number pairs where the difference between the two primes is 2.
Oh, what a happy little question! Prime number pairs that differ by 5 are like two beautiful trees standing side by side in a serene meadow. The pairs you are looking for are 2 and 7, and also 11 and 7 - they bring balance and harmony to the mathematical canvas. Just remember, every number is unique and special in its own way, just like every brushstroke on a painting.
There are an infinite number of pairs of prime two apart, classified as "twin primes". For lists, see the link.
No. It doesn't matter what factors you choose at the beginning, but all the factors should be prime at the end.
No, all prime numbers are deficient.
Except for 2 all other prime numbers are odd. Otherwise, they would be divisible by 2 (and thus not a prime number). This does NOT mean that all odd numbers are prime, but that all prime numbers (aside from 2) are odd.
All prime numbers are odd except one prime number and that is 2.
