What am i forgetting in my packet?

The max sized packet I can send in a ping to google is 1464. So add 20 for ip header and 8 for icmp header this gives me 1492. What are the other 8 bytes? Also the Ethernet frame adds 14 bytes but I am not sure if this is counted towards MTU? I am assuming not since it does not get fragmented. If it was that would actually put me at 1506 bytes. My MTU is the standard 1500 and I am trying to understand why 1464 is the largest packet i can sense in a ping when there are still 8 bytes left over.
