One characterization of the irregular primes is as follows:

For an irregular prime $p$, there exists some natural number $kle fracp-32$ such that $p$ divides [the numerator of] $B_2k$ where $B_2k$ is a Bernoulli number.

Question: Is there some prime $p$ for which there exists some natural number $kle fracp-32$, such that $p^2$ divides $B_2k$?
