Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541732, here are decompositions:

73 + 31541659 = 31541732
151 + 31541581 = 31541732
163 + 31541569 = 31541732
223 + 31541509 = 31541732
283 + 31541449 = 31541732
331 + 31541401 = 31541732
373 + 31541359 = 31541732
463 + 31541269 = 31541732

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.73.228.

Address: 1.225.73.228
Class: public
IPv4-mapped IPv6: ::ffff:1.225.73.228

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.
