What's so special about 619603547897^42?

Last month I presented a record large (338-digit) 35-balanced factorization integer:

  8466772177^34   <338>   k=35

A week later I came across a slightly bigger one:

828145091789^29   <346>   k=36


619603547897^42   <496>   k=51

The 496-digit integer joined with the 14 digits of its factorization contains exactly 51 each of the ten decimal digits!
