Place eggs in a saucepan and cover with water. Bring to a boil, then cover and remove from heat. Let stand for 12 minutes. Transfer eggs to an ice bath to cool.
Peel the eggs and slice them in half lengthwise. Remove yolks and place in a bowl.
Mash the egg yolks with mayonnaise, Dijon mustard, garlic powder, kosher salt, and paprika until smooth.
Finely chop the extra shrimp and fold into the yolk mixture.
Spoon or pipe the yolk mixture back into the egg whites.
Garnish each deviled egg with a whole shrimp, a sprinkle of paprika, and a pinch of minced parsley.
