The primary key is a signing DSA type 1024 bits long, the encryption
ElGamal subkey is 4096 bits long.

As they are doing two different jobs the lengths need not be the same.

Have a look at
for a brief comment on the lengths.

I'm sure there are other more elucidating documents available if you
look around a bit.
