Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476072, here are decompositions:

13 + 31476059 = 31476072
41 + 31476031 = 31476072
59 + 31476013 = 31476072
109 + 31475963 = 31476072
163 + 31475909 = 31476072
223 + 31475849 = 31476072
293 + 31475779 = 31476072
359 + 31475713 = 31476072

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.73.104.

Address: 1.224.73.104
Class: public
IPv4-mapped IPv6: ::ffff:1.224.73.104

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.
