The block reward here is 50.04 BTC instead of 50. Why is this so? I notice many blocks have this slight excess.

user44760: The coinbase transaction(the transaction that pays miner bitcoins) gets bitcoins from two sources. 

Block reward: This part goes on declining like 50/25/12.5 and so-on in a pre-defined schedule
transaction fees: This part is total sum of all transaction fees of all transactions in the that particular block. This is determined by market conditions.

Miner Income =  Block-reward + Transaction fees

user59445: Transaction fees are not counted as newly generated coin. Here new is 50 but 04 is your total transaction fees. As a total reward it is 50.04 but newly generated only 50.
