Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468488, here are decompositions:

17 + 31468471 = 31468488
41 + 31468447 = 31468488
89 + 31468399 = 31468488
97 + 31468391 = 31468488
151 + 31468337 = 31468488
157 + 31468331 = 31468488
199 + 31468289 = 31468488
229 + 31468259 = 31468488

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.43.200.

Address: 1.224.43.200
Class: public
IPv4-mapped IPv6: ::ffff:1.224.43.200

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.
