Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475604, here are decompositions:

5 + 31475599 = 31475604
7 + 31475597 = 31475604
23 + 31475581 = 31475604
113 + 31475491 = 31475604
151 + 31475453 = 31475604
197 + 31475407 = 31475604
211 + 31475393 = 31475604
233 + 31475371 = 31475604

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.71.148.

Address: 1.224.71.148
Class: public
IPv4-mapped IPv6: ::ffff:1.224.71.148

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.
