However I notice the sum of the first five prime numbers beginning one prime earlier (389) does add up to 2015, thus:  389 + 397 + 401 + 409 + 419 = 2015 and the difference (10) can easily be found by differencing nearby primes.

It would be interesting to know if this erroneous result reflects some internal glitch in Perplexity's architecture, and how it arose.

And my best wishes to Linkers for a peaceful, if interesting, 2025 whatever its' numerical significance!  I'd like to live for the next 100 years just to see how it all turns out....
