What is "perfect prime"? If it is simply prime, then this sequence is
likely to be finite by Goldbach conjecture.
Moreover, Vinogradov actually proved that all sufficiently large odd
numbers are the sums of three primes. So, for sure we can say at least
that there is only a finite number of odd numbers in this sequence.
