Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467560, here are decompositions:

79 + 31467481 = 31467560
127 + 31467433 = 31467560
193 + 31467367 = 31467560
331 + 31467229 = 31467560
379 + 31467181 = 31467560
433 + 31467127 = 31467560
457 + 31467103 = 31467560
571 + 31466989 = 31467560

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.40.40.

Address: 1.224.40.40
Class: public
IPv4-mapped IPv6: ::ffff:1.224.40.40

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.
