2011: A Prime Year

The year 2011 was quite remarkable, numerically speaking at the very least.  Here are some interesting facts about the number 2011.

First and foremost, 2011 is prime.  The last prime-numbered year was 2003 and the next will be 2017 (thank you WolframAlpha!).

What is more interesting is that 2011 is a prime that is the sum of eleven consecutive prime numbers!  This was first pointed out by @mathematicsprof.

Afterwards, it was pointed out by @republicofmath that 2011 is expressible as another sum of consecutive primes!

When will we see such a numerically interesting year again?
