GIMP opened this 4000x2000 pixels original image in a 1000x500 px frame at zoom 12.5. This is a screenshot scaled to 400x200 px.

Open the Panorama Projection filter. Only the central part of the image is visible. Pan across the image to find your panorama using the Pan option or click and dragging. You can zoom in to have a wider view.
