Unique team numbers

[tagger]

I'm curious to see everyone post their team number and something that makes it a "cool" number.

Ours is 2357.
-It is the concatenation of the first 4 primes.
-The smallest four-digit prime whose distinct digits are primes.
-Letting A = 1, B = 2, ..., Z = 26, then 2357 is the sum of all the values of the U.S. Presidents' last names from Washington to Coolidge.
-2^2 + 3^3 + 5^5 + 7^7 is prime.
-2357 is also the sum of consecutive primes in at least two ways: (773 + 787 + 797) and (461 + 463 + 467 + 479 + 487).
-The smallest number, curiously prime, whose square begins with 4 identical (prime) digits: 2357^2 = 5555449.
-23:57 is the largest prime on a military (or twenty-four hour) clock.
-2^1013 + 3^1013 + 5^1013 + 7^1013 is prime.
-2^19 + 3^19 + 5^19 + 7^19 is prime.
-The prime digits united by unities is prime (2131517).
-2*3*5*7+2+3+5+7 and 2*3*5*7-2-3-5-7 are both prime.
-The only integer that is both a concatenate prime and a minimal k-primeval prime.
-100^n + 10^n - 1 is prime for consecutive primes 2-3-5-7.
-The product of the primes less than or equal to 2357 is the smallest titanic primorial number.
