k*(k+1) + k*(k-1) == 2k^2

So you seem to be out by a factor of 2 somewhere.

Factoring in that factor of two...

Table[{k,
k^2,
Prime[k^2],
(Prime[k^2]+1)/2,
PrimePi[(Prime[k^2]+1)/2],
k*(k+1)/2},
{k, 4, 8}]

{{4, 16, 53, 27, 9, 10},
{5, 25, 97, 49, 15, 15},
{6, 36, 151, 76, 21, 21},
{7, 49, 227, 114, 30, 28},
{8, 64, 311, 156, 36, 36}}

You seem to be saying the last two columns are the same.
I beg to differ.

Let's look a bit further, at the data for k=100000-100005:

{
{100000, 10000000000, 252097800623, 126048900312, 5141644677,
5000050000},
{100001, 10000200001, 252103045511, 126051522756, 5141747035,
5000150001},
{100002, 10000400004, 252108316073, 126054158037, 5141850524, 5000250003},
{100003, 10000600009, 252113577847, 126056788924, 5141953182, 5000350006},
{100004, 10000800016, 252118846391, 126059423196, 5142056263, 5000450010},
{100005, 10001000025, 252124112327, 126062056164, 5142159097, 5000550015}
}

The last 2 columns really aren't that similar.

These messages about Goldbach's Conjecture are not
supposed to be to this mailing list (also the Riemann Hypothesis).

There are separate mailing lists for these.

Kermit says.

Milton! You surprise me.

Goldbach's conjecture IS about prime numbers. It's doesn't matter that
there exist mailing lists specifically about Goldbach's conjecture.
