Cook the orzo in salted boiling water, about 8–9 minutes. Drain and toss with olive oil, lemon juice, garlic powder, oregano, and salt.
Pat the salmon dry and season with oregano, paprika, salt, and pepper. Heat olive oil in a skillet over medium heat. Cook skin-side down for 4–5 minutes, then flip and cook 3–4 more minutes.
During the last minute, add garlic and lemon juice to the pan and spoon the oil over the salmon. Remove from heat and break into chunks.
