I was obtaining 34 for 7e4 too, but it's not a problem of the test suite. It just means that your code is not testing all possible combinations (and there are probably other numbers that will fail too). There is no known algorithm to generate the list of integer complexity (https://oeis.org/A005245), which means brute force is the only way to be sure. And brute force finds 32 for 7e4.
It someone doesn't believe 7e4 = (1+1)*(1+1)*(1+1)*(1+1)*(1+ (1+1)*(1+1+1)*(1+1+1)*(1+1+1)*(1+1+1)*(1+1+1)*(1+1+1)*(1+1+1)) (32 ones). Or 2^4*(1 + 2*3^7).
