Special alignment about split environment

I have some trouble in formatting my formula, so far I am able to get it look like this:

What I want is this:

Here is my MWE I am using split, I don't think I can use align because it will break my formulas into smaller ones.

\everymath{\scriptstyle}
\begin{equation}
\begin{split} 
&\forall \boldsymbol{value_{1}}, \boldsymbol{value_{2}}, \boldsymbol{value_{3}}     \textsf{Relationship(}\boldsymbol{value_{1}},\boldsymbol{value_{2}},\boldsymbol{value_{3}}\textsf{)} \to \\
&    \textsf{Unary(}\boldsymbol{value_{1}},\boldsymbol{value_{2}},\boldsymbol{value_{3}}\textsf{)} \vee \\
&    \textsf{Binary(}\boldsymbol{value_{1}},\boldsymbol{value_{2}},\boldsymbol{value_{3}}\textsf{)} \vee \\
&    \textsf{Ternary(}\boldsymbol{value_{1}},\boldsymbol{value_{2}},\boldsymbol{value_{3}}\textsf{)}
\end{split} 
\end{equation}
