Let's have some fun with higher order functions and instead of folding over a list, fold over the prime factors of a number. It can be optimized further by dividing out real primes instead of numbers of the form 6k+/-1, but it's not embarrassingly slow.

A prime Eratosthenes' sieve, using a bit array and sieving only odd composites to conserve memory and keep things fast.
