Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622130, here are decompositions:

11 + 31622119 = 31622130
17 + 31622113 = 31622130
83 + 31622047 = 31622130
149 + 31621981 = 31622130
151 + 31621979 = 31622130
167 + 31621963 = 31622130
173 + 31621957 = 31622130
181 + 31621949 = 31622130

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.131.242.

Address: 1.226.131.242
Class: public
IPv4-mapped IPv6: ::ffff:1.226.131.242

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.
