Be careful, I've implemented the sieve, but not all versions of it are sufficiently fast to handle the biggest numbers in the test suite.

This doesn't use primes(x),but still feels a little like cheating.

The whole point of using the sieve is not knowing which numbers are prime. So it is no different than sum(primes).
