Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453464, here are decompositions:

17 + 31453447 = 31453464
37 + 31453427 = 31453464
43 + 31453421 = 31453464
71 + 31453393 = 31453464
73 + 31453391 = 31453464
103 + 31453361 = 31453464
131 + 31453333 = 31453464
181 + 31453283 = 31453464

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.223.241.24.

Address: 1.223.241.24
Class: public
IPv4-mapped IPv6: ::ffff:1.223.241.24

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.
