Pity it wasn't in Feb for the challenge, and I just missed International Women's Day too (as it's a Sophie Germain one), and it's not in the top 5,000, but happy to have finally got one anyway!

Congratulations! Our records indicate that a computer registered by you has found a unique prime number. This computer is assigned to the Sophie Germain (LLR). Since candidates on this subproject are not large enough to report to the Top 5000 Primes List, your prime is visible immediately.
