1) Relation to multiples of 6: Every prime number greater than 3 is always one less or one more than a multiple of 6.
Example: `24137` is 1 less than `24138` (multiple of 6).

2) Square minus 1 divisible by 24: For every prime number greater than 3, if 1 is subtracted from its square, the result is always divisible by 24.
Example: The square of `24137` is `582594769`. Subtracting 1, we get `582594768`. Note that `582594768 ÷ 24 = 24274782`.

3) Difference of squares: Every prime number greater than 2 can be expressed as the difference of the squares of two consecutive natural numbers.
Example: `24137 = 12069^2 - 12068^2 = 145660761 - 145636624`

4) Sum of two squares: Every prime number of the form `4n+1` (where n is a positive natural number) can be expressed as the sum of two squares.
Example: `24137 = 44^2 + 149^2 = 1936 + 22201`, where `24137 = 4 × 6034 + 1`.

5) Form `4n+1` or `4n-1`: Except for the number 2, all prime numbers follow the pattern `4n+1` or `4n-1`, where `n` is a natural number.
Example: `24137` is of the form `4n+1`, where `n = 6034`.
