What happens to breast implants after you die? So they decompose with the body or will they last with your skeleton for thousands of years?

The materials for medical implants are chosen because they are inert and non-biodegradable. They will not decompose when the biological parts of the body do. 

Future archaeologists who excavate our graveyards will find many bodies that still have pacemakers, artificial hips, titanium plates, and, yes, breast implants. 

Modern saline implants have a valve, which could leak and let the fluid out, but the silicone implant capsule itself would remain.
