Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566924, here are decompositions:

5 + 31566919 = 31566924
13 + 31566911 = 31566924
23 + 31566901 = 31566924
61 + 31566863 = 31566924
97 + 31566827 = 31566924
107 + 31566817 = 31566924
127 + 31566797 = 31566924
131 + 31566793 = 31566924

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.172.76.

Address: 1.225.172.76
Class: public
IPv4-mapped IPv6: ::ffff:1.225.172.76

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.
