19- tuple search

There is, currently, no known 19-tuple with pattern
[0, 4, 6, 10, 12, 16, 24, 30, 34, 40, 42, 46, 52, 54, 60, 66, 70, 72, 76]
I wrote some attached search code, but I think it is too slow.
from the pzktupel.de webpage, I estimate that the prime number is about 10^27, comparing with other 19 tuplels.
I was able to search to 10^12 after an hour and a half. At that rate, it would take years to find the prime.
I will search for a few days, and see what I find.

Not known? Really?

What is this then?
Code:
622803914376064301858782434517 + d,
d = 0, 4, 6, 10, 12, 16, 24, 30, 34, 40, 42, 46, 52, 54, 60, 66, 70, 72, 76
