Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594404, here are decompositions:

5 + 31594399 = 31594404
11 + 31594393 = 31594404
31 + 31594373 = 31594404
53 + 31594351 = 31594404
71 + 31594333 = 31594404
73 + 31594331 = 31594404
131 + 31594273 = 31594404
157 + 31594247 = 31594404

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.23.164.

Address: 1.226.23.164
Class: public
IPv4-mapped IPv6: ::ffff:1.226.23.164

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.
