Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622732, here are decompositions:

3 + 31622729 = 31622732
19 + 31622713 = 31622732
61 + 31622671 = 31622732
103 + 31622629 = 31622732
223 + 31622509 = 31622732
241 + 31622491 = 31622732
439 + 31622293 = 31622732
601 + 31622131 = 31622732

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.134.76.

Address: 1.226.134.76
Class: public
IPv4-mapped IPv6: ::ffff:1.226.134.76

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.
