Just making sure you are aware that k values 2704, 61009, and 786615 can be eliminated from the conjecture, 2704 due to 52^2 and 541 on odd n, 786615 due to 15*229^2 and 541 on even n, and 61009 due to the below algebraic factorization.
All k where k = m^2 and k == 9550 or 7603 mod 17153:
for even n let k = m^2 and n = 2*q, factors to:
(m*540^q-1)(m*540^q+1)
odd n:
covering set 17, 1009

Impressive work figuring out k=61009. I definitely would not have found that one. The new srsieve may or may not have found it.
