Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467256, here are decompositions:

5 + 31467251 = 31467256
53 + 31467203 = 31467256
89 + 31467167 = 31467256
167 + 31467089 = 31467256
173 + 31467083 = 31467256
257 + 31466999 = 31467256
263 + 31466993 = 31467256
383 + 31466873 = 31467256

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.38.248.

Address: 1.224.38.248
Class: public
IPv4-mapped IPv6: ::ffff:1.224.38.248

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.
