EXAMPLE

The smallest prime number is 2, the smallest Fibonacci number is 0; hence 1 can't be presented as a sum of a prime number and a Fibonacci number.


MATHEMATICA

nn = 17; f = Union[Fibonacci[Range[0, nn]]]; p = Prime[Range[PrimePi[f[[1]]]]]; fp = Select[Union[Flatten[Outer[Plus, f, p]]], # < f[[1]] &]; Complement[Range[f[[1]]  1], fp] (* T. D. Noe, Mar 06 2012 *)
