A132146 Numbers that can't be presented as a sum of a prime number and a Fibonacci number (0 is not considered to be a Fibonacci number).
1, 2, 17, 29, 35, 59, 83, 89, 119, 125, 127, 177, 179, 208, 209, 221, 239, 255, 269, 287, 299, 329, 331, 353, 359, 363, 389, 416, 419, 449, 479, 485, 509, 515, 519, 535, 539, 547, 551, 561, 567, 569, 599, 637, 659, 673, 697, 705, 718, 733, 739, 755, 768, 779
