Table schema:
CREATE TABLE table_name_67 (bronze VARCHAR, silver VARCHAR, nation VARCHAR, total VARCHAR, rank VARCHAR)

Question: How many bronze numbers had a total of more than 4 when the rank is less than four, germany is involved, and there's less than 5 silver?
SQL: SELECT COUNT(bronze) FROM table_name_67 WHERE total > 4 AND rank < 4 AND nation = "germany" AND silver < 5
