Try heating it up and applying some fresh, lower-melting-point
solder... 63/37 comes to mind, or even ChipQuik (which might be
excessively expensive for this). A drop of rosin flux, first, might
be a good idea.

There's a fair chance that the new solder, once liquid, will begin to
dissolve away the high-temperature silver, forming a eutectic whose
melting point will still be within the range of your iron or torch.
Vacuum-bulb away the eutectic, and repeat the operation to dissolve
the next layer of silver.
