GIMPS has discovered a new largest known prime number: 282589933-1 (24,862,048 digits)

+ The smallest multidigit number that is not the sum of a prime and a power.

+ US Airways Flight 1549 famously splash landed in the Hudson river. 1549 is prime, and, curiously, 15491152009 is also prime, which concatenates the flight number with the flight date 1/15/2009. [Post]

+ The number of different ways a quarter can be tendered in exact change using legal coins produced by the United States Mint since its inception. (Relevant denominations $0.25, $0.20, $0.10, $0.05, $0.03, $0.02, $0.01, and $0.005). [Goelz]

(There is one curio for this number that has not yet been approved by an editor.)
