Conditional Formatting for three columns range and their sum

Question

My Input:

A   B   C
5   2   3
5   2   4

I want to conditionally format the row such as if A is not equal to B+C, then the entire row should be highlighted in red. In my case, second row should be highlighted as 5 != 2 + 4.

What I tried is adding a custom formula to the range - A2:C and the formula I tried is:

=A3 <> SUM(B3, C3) and some other ways, but couldn't figure it out.

PS: I want to create this formatting check for the entire column not just for a single row.

Any help is appreciated. Thanks.

Thanks to @Sergey's comment. The working formula is =$A2<>SUM($B2:$C2) for the range A2:C.
