Get name and not value of a multi-dimensional array?

So, in this scenario I have a multi-dimensional array that is in a module script. I have a localscript that is accessing that module script. It is correctly requiring and getting the sub-array, except it only gives the value and not the name. For example, if I had this array:

local Random = {
	Another = {
		Blank1 = 1,
		Blank2 = 2,
		Blank3 = 3,
	},
	Something = {
		Filled1 = 4,
		Filled2 = 5,
		Filled3 = 6,
	},
}

And I wanted to get the names of the sub-array's children. So for example, let's say I was checking if the values was 2, this is what I would do. Also, let's assume for all purposes that the local and everything else is already set-up so that it connects together.

for i, v in pairs(Random.Another) do
	if v == 2 then
		return v
	end
end

However, what I would want it to do is return Blank2, and not the value (or number). How would I do this?
