Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592464, here are decompositions:

11 + 31592453 = 31592464
17 + 31592447 = 31592464
41 + 31592423 = 31592464
47 + 31592417 = 31592464
53 + 31592411 = 31592464
107 + 31592357 = 31592464
173 + 31592291 = 31592464
251 + 31592213 = 31592464

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.16.16.

Address: 1.226.16.16
Class: public
IPv4-mapped IPv6: ::ffff:1.226.16.16

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.
