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.
While evaluating the solution, the server encountered an error caused by long running MATLAB code. Edit the code if needed and then submit.
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).
