Since the distance between the centres of the two objects decrease as we go down ,,shouldn't acceleration due to gravity increase..
(as per the equation g=GM)...?

Why does acceleration due to gravity decrease as one goes down to the core of the earth..?

Initially, as you begin to move down towards the center of the Earth, the g force will go increase, but as you continue down, it will begin to eventually decrease unitl it reaches zero at the center mainly because as you move closer to the center, the decreasing percentage of the Earth's mass contibuting to the force becomes a larger factor than your decreasing distance from the center.
