Is 8795 especially uninteresting

Well, these are ugly, base, and dumb, but do give us 8795 in two
different ways related to semiprimes:

=============

Numbers whose decimal representation concatenates two integers each a
semiprime which is the sums of 4 but no fewer nonzero squares.

1515, 1539, 1555, 1587, 1595, 3915, 3939, 3955, 3987, 3995, 5515,
5539, 5587, 5595, 8715, 8739, 8755, 8787, *** 8795 ***...

Cf. A121051

=============

Numbers whose decimal representation concatenates two integers each a
number n such that n, n-1 and n-2 are semiprimes.

3535, 3587, 3595, 8735, 8787, *** 8795 ***,  9535, 9587, 9595, ...
