Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467120, here are decompositions:

17 + 31467103 = 31467120
31 + 31467089 = 31467120
37 + 31467083 = 31467120
53 + 31467067 = 31467120
109 + 31467011 = 31467120
127 + 31466993 = 31467120
131 + 31466989 = 31467120
151 + 31466969 = 31467120

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.38.112.

Address: 1.224.38.112
Class: public
IPv4-mapped IPv6: ::ffff:1.224.38.112

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.
