Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547464, here are decompositions:

5 + 31547459 = 31547464
23 + 31547441 = 31547464
107 + 31547357 = 31547464
167 + 31547297 = 31547464
197 + 31547267 = 31547464
233 + 31547231 = 31547464
317 + 31547147 = 31547464
401 + 31547063 = 31547464

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.96.72.

Address: 1.225.96.72
Class: public
IPv4-mapped IPv6: ::ffff:1.225.96.72

Public, routable address (assignable to a host on the internet).

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
