All,

Let pₙ = the n-th prime.

Then 2023
= 7∙17²
= p₄∙p₇²
= p_{p₁^p₁} ∙ {p_{p₄}}^{p₁}
= p_{p₁^p₁} ∙ {p_{p_{p₁^p₁}}}^{p₁}

No information is lost by dropping the terminal 1s.
Thus we may write the following form.

2023 = p_{p^p} ∙ {p_{p_{p^p}}}^p

Forms like those correspond to a family of digraphs
called “riffs” and a family of graphs called “rotes”,
as described in the following OEIS Wiki article.

Riffs and Rotes ( https://oeis.org/wiki/Riffs_and_Rotes )
