What is about the number 1? It is not the sum of a prime and a power either.
And the numbers 3 and 5 are such sums only if 0 is counted as a power.

I believe searching "1549 -_,1549" (without quotes) will do the trick.

It seems to be missing in OEIS. The next term is  1771561 = 11^6.
So the sequence starts with
1, 1549, 1771561
