This is not an update about life. Sue me or something.

Any prime number greater than 3 must be of the form 6n + 1 or 6n - 1. This kind of shows why twin primes are a natural concept. Furthermore, twin prime pairs greater than 25 must be of the form 6n - 1 and 6n + 1 with n not divisible by 3. I haven't worked out what restrictions occur when 7 is thrown into the mix after 49.
