The constant for the universe expansion is (70km/s)/Mpc, so if we approximate MW-Andromeda to be 1 Mpc, in a million years it would be ~233 light years further. In real life, thought, it has a relative speed towards us and the gravitational bound between our galaxy and Andromeda is enough to render the expansion useless
