Could you pls remind me how do I decompose arbitrary 4x4 matrix into Dirac 16 matrices...

I ve forgotten.

Thank you

But not every 4x4 matrix is a sum of gamma matrices.

I don't know how to answer Neitrino's question, but I think Neitrino is asking about using the gamma matrices and their products to form a basis for the 16-dimensional vector space of 4x4 matrices. Usually, this space is written as a direct sum of subspaces of dimensions 1, 4, 6, 4, 1.
