22478...55659 (4940-digits)

This number is a probable-prime (likely to be a prime but we have not (re-)proven it on this site).

The number (59^61 + 2374 * (59+60)^2374) is a prime of mixed exponential structure, combining a prime power term (59^61) with a scaled large exponential component (2374 * 120^2374). It is notable for its compact algebraic form involving two distinct exponentiation patterns and for arising from experimentation with prime generating expressions. [Amine]
