Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525224, here are decompositions:

11 + 31525213 = 31525224
13 + 31525211 = 31525224
23 + 31525201 = 31525224
41 + 31525183 = 31525224
47 + 31525177 = 31525224
61 + 31525163 = 31525224
97 + 31525127 = 31525224
103 + 31525121 = 31525224

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.9.104.

Address: 1.225.9.104
Class: public
IPv4-mapped IPv6: ::ffff:1.225.9.104

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.
