What’s the best way to make a text field with a suggested value that is shown even after it is filled?

For example, let’s imagine a simple exercise tracking app. There’s a field where the user can input the target score (the score he wishes to obtain).

Then, after exercising, the user is presented a field asking what score was actually obtained. On the same field, I need a way to show the "target" value, as well as the input value.

For now, I’ve thought of showing the target value as a suffix, but I fear it isn’t obvious.

Example of field with suggested value

I could also simply show the target value in the field’s label: "Score (1000)"

Is there a more user-friendly approach? thank you
