primes in A006128

[Jonathan Post]

It seems to me that primes are fairly sparse in at least the smaller
values of A006128  Total number of parts in all partitions of n. Also,
sum of largest parts of all partitions of n.

a(2) = 3,
a(30) = 54563,
a(49) = 2351597,
a(54) = 5584141,
a(56) = 7805507.

The seque4nce does not itself involve primes, so there's probably not
much point in submitting "primes in A006128" -- correct?
