2011!

Remarkably, 2011 is the sum of 11 consecutive prime numbers! 

2011 = 157 + 163 + 173 + 179 + 181 + 191 + 193 + 197 + 199 + 211

And of course 2011 is itself a prime number!

What a great prospect for a prime year — our very best wishes to you.

    How is this possible?
     
    the string (157 + 163 + 173 + 179 + 181 + 191 + 193 + 197 + 199 + 211)  equals 1844 but not 2011.
    A number is missing here, which is not a prime number, but a happy number:

    Thanks for catching that! You mean not only a prime but also a happy number, I think. And it just looks cool
