mysql – Remove tables intersection

Given two columns, t1 with distinct values, but a superset of t2, how is it possible to operate over t1 to subtract the elements of t2 of t1? I utilize MySQL 5.7

CREATE TABLE IF NOT EXISTS t1 (
   id_ INTEGER  NOT NULL,
   value1 INT NOT NULL
INSERT INTO t1 (id_, value1) VALUES
(1),
(2),
(3),
(4),
(5),
(6),
(7),
(8)

CREATE TABLE IF NOT EXISTS t1 (
   id_ INTEGER  NOT NULL,
   value1 INT NOT NULL
INSERT INTO t2 (id_, value2) VALUES
(1),
(2),
(3),
(4)
