Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472364, here are decompositions:

5 + 31472359 = 31472364
13 + 31472351 = 31472364
71 + 31472293 = 31472364
73 + 31472291 = 31472364
103 + 31472261 = 31472364
163 + 31472201 = 31472364
173 + 31472191 = 31472364
181 + 31472183 = 31472364

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.58.236.

Address: 1.224.58.236
Class: public
IPv4-mapped IPv6: ::ffff:1.224.58.236

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.
