Ian, true, I could have summed it that way.

I quit when the sum is greater than the last prime because I wouldn't be able to verify if the sum was a prime (I don't want to write any verification algorithms myself. I just want to use that primes.txt list).

And you are right about primes at the end of the list, this wouldn't find it. You'd need a bigger prime list 450 million primes.
