# [seqfan] Re: Sequence of the sum of primes = prime but with a twist.

```You have to exclude 2 from the sequence. Otherwise, the first sum is 2,
that's a prime, so we leave it out. Now the next sum is 3, etc. You
wind up with all the primes.

A note should be included that 2 is to be skipped.

Neil,

I am not sure if the 2 belongs as the start of this sequence.
After this gets resolved and I can produce a larger number of
terms I will submit it.

Thanks,

Dan
