How to make shuffled number never equal original? (Java)

I have an original number (LoadG1). I then produce shuffled versions of this number as seen in the code below. Note: generateG1 is a Random.

int loadG1 = generateG1.nextInt(89999) + 10000;
for (int allrbA = 0; allrbA < 4; allrbA++) {

StringBuilder charLoadG1 = new StringBuilder(String.valueOf(loadG1));
StringBuilder randomLoadG1 = new StringBuilder();
while(charLoadG1.length() != 0) {
int index = generateG1.nextInt(charLoadG1.length());
char c = charLoadG1.charAt(index);
randomLoadG1.append(c);
charLoadG1.deleteCharAt(index);
}

}

This successfully rearranges the numbers in loadG1, seen as the value for randomLoadG1. The issue is, I don't want randomLoadG1 to ever be == to loadG1. This can happen if it is rearranged into the exact same order. I tried using a while loop to sort this out, but it only crashed my app whenever an identical randomLoadG1 was produced.

Can anyone help out with explaining how to get randomLoadG1 (the shuffled version(s) of the original loadG1) to never have the same value as loadG1? Any submitted code is greatly appreciated, many thanks.
