If the water the fish is in is not changed regularly a goldfish will do this because the oxygen in the water is too low for the fish to absorb it through its gills so it gulps air from the surface of the water. Make sure you change the water in a fish bowl or get an air bubble pump for an aquarium and this will stop this behavior in your goldfish.
Goldfish always go to the top for oxygen. They are known to do this. This is why it is recommended you do not have a really tall tank. I have gold fish and never have a tank over 16 inches tall. In my 40 gallon that is 36" Long x 16" High x 18 " Deep. I have two gold fish that are about 3 inched long in size. But one is a black moor. Both go to top for oxygen even though I have two filters, a 45 and 40, plus two sponge bubbler filters, and two long bubblers in back of aquarium. They are quite healthy and never sick. In fact I saved them from Walmart some time ago. I do know it is better to have a tank that is not tall and goldfish will always go to the top for oxygen. They require more oxygen than many fish. I have another 4 foot long tank that is only 12.5 inches tall with black moors. They too, (as a species of gold fish) go to the top for oxygen. I keep water in top perimeters. and water change as needed. But if your fish show floating signs, give the fish peas. I give my fish peas once a week to keep them from having a swim bladder issue, but if they do, peas cure over night.
Try to have moving water as this creates oxygen. Try to have a tank that is not too tall. I have been told it is best to feed goldfish grandular food or pettet food. Not Flakes! My research has told me flakes can cause swim bladder issue in goldfish..
