some primes I found with Proth.exe last year

They're probably not worthy at all, but here they are:

847*2²⁴²⁰+1
5325*2³⁶⁶⁰+1
8587*2³⁶⁶⁰+1
10803*2³⁶⁶⁰+1
1617*2⁶⁸⁰⁰+1
2113*2⁶⁸⁰⁰+1
3753*2⁶⁸⁰⁰+1
5161*2⁶⁸⁰⁰+1
963*2¹²³⁵⁰+1

I don't see anything notable about them. BTW, Proth is old and very slow compared to LLR/PRP/PFGW. If you want to find large primes, i.e. large enough for the Top-5000, use one of those instead.

If you have an interest in a project that searches for large primes, there are many of them out there. Some require you to run their software, but others allow you to choose the software you want to run. Just ask and many people on the forum will promote their project or others.
