Question: How many teams playing in divisions in Greece have ever scored 4 or more goals?
SQL: SELECT COUNT(DISTINCT CASE WHEN T1.FTHG >= 4 THEN HomeTeam ELSE NULL end) + COUNT(DISTINCT CASE WHEN T1.FTAG >= 4 THEN AwayTeam ELSE NULL end) FROM matchs AS T1 INNER JOIN divisions AS T2 ON T1.Div = T2.division WHERE T2.country = 'Greece'
