Satoshi’s coinbase transaction

The Satoshi’s coinbase transaction includes this following scriptSig:

04ffff001d0104455468652054696d65732030332f4a616e2f32303039204368616e63656c6c6f72206f6e206272696e6b206f66207365636f6e64206261696c6f757420666f722062616e6b73

There’s an unexpected thing that I don’t fully understand. What is this bytes sequence:
04ffff001d0104. Like that, I could eventually determine as 04 (size) + ffff001d + 01 (size) + 04

But I don’t think it’s the decode structure, so are you able to tell me what is this sequence number and what is its role ?
