Yes, this looks ok :)

The 'e' partition can only start *after* the 'd' partition, so it should
have an offset of:


    'd' start  + 'd' size
    ---------    --------
    3121152    + 2097152  = 5218304

The 'rest' of the disk is:

    'c' size   - 'e' start
    --------     ---------
    8916012    - 5218304   = 3697708
