Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567004, here are decompositions:

31 + 31566973 = 31567004
37 + 31566967 = 31567004
103 + 31566901 = 31567004
211 + 31566793 = 31567004
241 + 31566763 = 31567004
373 + 31566631 = 31567004
457 + 31566547 = 31567004
463 + 31566541 = 31567004

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.172.156.

Address: 1.225.172.156
Class: public
IPv4-mapped IPv6: ::ffff:1.225.172.156

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.
