Wright's Fourth Prime

Wright proved that there exists a number $c$ such that if $g_0 = c$ and $g_{n+1} = 2^{g_n}$, then $\lfloor g_n \rfloor$ is prime for all $n > 0$. Wright gave $c = 1.9287800$ as an example. This value of $c$ produces three primes, $\lfloor g_1 \rfloor = 3$, $\lfloor g_2 \rfloor = 13$, and $\lfloor g_3 \rfloor = 16381$. But with this $c$, $\lfloor g_4 \rfloor$ is a 4932-digit composite number. However, this slightly larger value of $c$, $$c = 1.9287800 + 8.2843 \cdot 10^{-4933},$$ reproduces Wright's first three primes and generates a fourth: $$\lfloor g_4 \rfloor = 191396642046311049840383730258 \text{ } \ldots \text{ } 303277517800273822015417418499$$ is a 4932-digit prime. Moreover, the sum of the reciprocals of the primes in Wright's sequence is transcendental.
