Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567020, here are decompositions:

41 + 31566979 = 31567020
47 + 31566973 = 31567020
53 + 31566967 = 31567020
101 + 31566919 = 31567020
109 + 31566911 = 31567020
157 + 31566863 = 31567020
181 + 31566839 = 31567020
193 + 31566827 = 31567020

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.172.172.

Address: 1.225.172.172
Class: public
IPv4-mapped IPv6: ::ffff:1.225.172.172

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.
