In triangle \( \triangle ABC \), the angles are \( \angle B = 30^\circ \) and \( \angle A = 90^\circ \). Point \( K \) is marked on side \( AC \), and points \( L \) and \( M \) are marked on side \( BC \) such that \( KL = KM \) (point \( L \) lies on segment \( BM \)).

Find the length of segment \( LM \), given that \( AK = 4 \), \( BL = 31 \), and \( MC = 3 \).
