This number is a prime.
FEMA designated Tropical Storm Isaac as EM-3347 for the period 8/26/12 to 9/10/12. Note that the sum of digits of the ending date, 3347, and the starting date, are three consecutive primes. [Goins]
The sum of the digits of 3347 is a prime which also happens to be both a Pythagorean prime and a emirp. The sum of the squares of the digits, the sum of the cubes of the digits, along with the sum of the biquadratics of the digits of 3347 are all prime as well! [Akash]
(There is one curio for this number that has not yet been approved by an editor.)
