Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476140, here are decompositions:

43 + 31476097 = 31476140
67 + 31476073 = 31476140
109 + 31476031 = 31476140
127 + 31476013 = 31476140
211 + 31475929 = 31476140
229 + 31475911 = 31476140
313 + 31475827 = 31476140
457 + 31475683 = 31476140

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.73.172.

Address: 1.224.73.172
Class: public
IPv4-mapped IPv6: ::ffff:1.224.73.172

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.
