Prime spiral

New project. Create a big prime spiral.

With haskell, I produced all primes under 10000. Let's see if we can put in all of them.

Here is the code I used.

isprime p= null [p | a<-[2..p-1], b<- [2..p-1], a*b==p]
primesinside a b = [p | p<- [a..b], isprime p]

To produce all primes under 10000, I write
primesinside 2 10000
