About 45 million coins have been DESTROYED of the premine. This occurred in transaction d6ab6f201c62c2a73981fc6f981a80742d552408bc70d53df30254a1e67a2727. This drops the premine down to a much more reasonable 5 million coins, which while still somewhat large, is no longer years worth of mining.
For reference, here is the transaction details. You can confirm that they were destroyed by the last vout of ~45 million being used for this transaction script: ""asm" : "OP_DUP OP_HASH160 0000000000000000000000000000000000000000 OP_EQUALVERIFY OP_CHECKSIG"," the long string of 0s means it is provably impossible to generate a public key matching this to spend the funds, and the funds are provably DESTROYED.
