It probably arrived at similar sizes due to different mechanisms. 
File header overhead (and deflate method overheads) is also 
significant for small files. I meant that it should not be any 
more compressible than an equivalent string of digits output by a 
strong encryption method.

sieve.number is compressed mainly by reducing the length of 
codewords to under 4 bits per symbol due to 10 symbols (digits), 
while the stream of digits itself has no real pattern and cannot 
be compressed via LZ coding.
