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

+ The smaller of only two 4-esthetic primes, i.e., primes whose successive digits differ by 4. The other is 95959. Note that the reversal of 15959 is a “4-esthetic brilliant number”, i.e., 95951 = 229 × 419. Can you find other such brilliant numbers? [Loungrides]
