%N A169790 Least number k having n unordered partitions into a nonzero Fibonacci number and a prime.
%C A169790 Variant of A168382.
%C A169790 Fibonacci(1) + prime(4) = Fibonacci(2) + prime(4) = Fibonacci(4) + prime(3) = Fibonacci(5) + prime(2) = 8 are two "distinct" representations of k=8, because Fibonacci(1) = Fibonacci(2) = 1 is treated as indistinguishable, and Fibonacci(4) = prime(2) = 3 are also indistinguishable: k = 1+7 = 3+5.
%C A169790 This matters because of the existence of Fibonacci primes (see A005478).
