Translation of epixoip's post: Your keyspace is too large for hashcat to handle, even the 64 bit version. There's not enough memory addresses. No you can't get more until an OS and hardware are made that support higher than 64 bits.
But even if there wasn't a memory limitation, it's still too large. Even if all the digits were known, a 12-character brute force isn't practical. The practical upper limit (currently) is about 6-7 characters. Maybe 8 with some really, really good hardware.
Unless there's some pattern to the second part you can use to narrow down the keyspace, it is uncrackable currently. The pattern could be "chosen by a human" rather than a computer generated random password with 95 possible characters in each position.
