This is a nice one! Congrats!

Does it mean there were no other primes between n=379559 and the exponent above? At this level of n it's not unusual at all but the gaps before were smaller...

No I have two computers working on it. n=395k to 450k is currently unsearched. I decided to put the faster computer to work at the top end of the range I have sieved (up to 500k).
