Overview
This site is a classic, minimal UPE calculator dedicated to very large even numbers.
It uses BigInt + Miller–Rabin to find the minimal symmetric Goldbach pair
(p, q) = (E/2 − t, E/2 + t) for even E up to 4×10^18.
The normalized displacement is f(E) = t / (log E)², and we display the nearest
known Riemann zero γ (read-only article linked below).

Tip: For very large E, t is usually small; BigInt Miller–Rabin keeps it fast.
