### Abstract

The row structures of the prime-subscripted Fibonacci numbers in the modular ring Z_{4} show distinction between primes and composites. The class structure of the Fibonacci numbers suggest that these row structures must survive to infinity and hence that Fibonacci primes must too. The functions *F _{p}* =

*K*± 1 and

_{p}*F*(factors) =

_{p}*k*± 1 support the structural evidence. The graph of (

_{p}*K*/

*k*) versus

*p*displays a Raman-spectra form persisting to infinity: ln(

*K*/

*k*) is linear in

*p*in the composite case while primes lie along the

*p*-axis to infinity.
