Combine marmalade, soy sauce, salt, black pepper, and garlic in a small bowl.
Arrange salmon fillets, skin sides down, on a foil-lined baking sheet coated with cooking spray. Brush the fish fillets evenly with half of the marmalade mixture. Bake the fish at 450 degrees for 4 minutes.
Heat the broiler to high (do not remove fish from oven); broil fish 6 minutes. Spoon the remaining marmalade mixture onto the center of each fillets. Broil fish an additional 3 minutes or until desired degree of doneness.
Sprinkle the fish evenly with green onions; serve with the lemon wedges.
