The problem of this contest was to sum up all numbers smaller than 1 000 000 which are not divisible by a number less then 100, but are not prime.
The solution is just a simple brute force calculation through all numbers.
Here is a simplified version of how you could have done it:
The result is then 22939817743 which is no prime as can be tested with the same prime tester.
