Perelman is a strange character; IIRC he declined several times first without bothering to give a reason. Then, after being asked enough times, came up with a "I am not a hero and such awards are irrelevant" as a somewhat acceptable version so those pesky folks would leave him alone. Thus I would not use him as an example of the right way to deal with a prestigious award.

That said, the Nobel medal to Trump circus is beyond ridiculous.
