@mt_ I am sorry, I don't know how I forgot to mention that. I have edited my answer. I hope it is better than the previous version.

comment Proving $n^4 + 4 n^2 + 11$ is $16k$
sos440's comment is better justified by noticing that if $n$ is even, then so is $n^4+4n^2$. Hence $n^4+4n^2+11$ has to be odd (since $11$ is an odd number).
