Edited to add:

Hey....593 ain't so bad after all. It is a special prime number whose square is greater than the product of its neighboring two primes - called a Good Prime. It is also a Right Prime because it remains prime after dropping any number of digits from the right...i.e. 593, 59, and 5 are all prime.

It is also the sum of seven consecutive primes (71 + 73 + 79 + 83 + 89 + 97 + 101) and the sum of nine consecutive primes (47 + 53 + 59 + 61 + 67 + 71 + 73 + 79 + 83).

Cool!
WOW! That's deep.
