Create a new transparent layer.
With the Paths Tool and the help of snapping, draw a triangle that represents the space you want subtracted (from one corner).
When the path is to your liking, call up a selection from the path and fill it with any colour.
Now duplicate this layer and flip it until you have a triangle in every corner.
Then merge these layers together.
Alpha select this layer and delete from the original (or apply a layermask from selection for non-destructive editing).
