For the blockexplorer result:
Most blockexplorers tend to correlate transactions with P2PK outputs to its P2PKH counterparts by deriving an address from that public key.
But it's not the proper way to show them, P2PK outputs should be searched in a blockexplorer by its TXID.
It may not be proper, but it's practical. Without it, people like OP may overlook the fact that they own a significant amount of Bitcoin.
