Is there a way to load a random decal?

So basically I've been trying to make a button that loads a random decal. Problem is, decals share the same IDs as models, places, etc...

I've tried doing a script, which keeps randomly choosing asset IDs until it finds a decal but it's not working for some reason.

 local ID = math.random(1, 73737627)
 local MarketplaceService = game:GetService("MarketplaceService")
 local productInfo = MarketplaceService:GetProductInfo(ID, Enum.InfoType.Product)          
 if productInfo.AssetTypeId == 7 then
 print("Success!")

Could somebody either help me with it or show me an alternate way? Thanks.
