Table schema:
CREATE TABLE table_name_72 (ofsted_number INTEGER, dcsf_number VARCHAR, intake VARCHAR, type VARCHAR, faith VARCHAR)

Question: What is the lowest Ofsted number for a primary with a CE faith, intake of 30 and a DCSF number lower than 3349?
SQL: SELECT MIN(ofsted_number) FROM table_name_72 WHERE type = "primary" AND faith = "ce" AND intake = 30 AND dcsf_number < 3349
