2011 is Prime Time

It’s been eight years coming, but finally, a year that’s a prime number. This hasn’t happened since 2003, but 2011 is prime.

Express 2011 as a sum of consecutive prime numbers.

That can be done in several different ways.

As it turns out, 2011 is extra cool because it can be written as a sum of a prime number of consecutive prime numbers.

When will that happen again?

And finally…

What is the next year that will be a prime number and also be a sum of a prime number of consecutive prime numbers? (Wow, that’s a mouthful, ain’t it?)

    Even more, it can be written as a sum of prime number of prime numbers in a prime number of ways😉.

    2011=157+163+167+173+179+181+191+193+197+199+211=661+673+677

    Answer to your question is 2081=401+409+419+421+431.

    Next year that will be writable as a sum of prime number of prime numbers in a prime number of ways is

    2179=71+73+79+83+89+97+101+103+107+109+113+127+131+137+139+149+151+157+163=719+727+733.
