Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504232, here are decompositions:

3 + 31504229 = 31504232
13 + 31504219 = 31504232
31 + 31504201 = 31504232
43 + 31504189 = 31504232
103 + 31504129 = 31504232
181 + 31504051 = 31504232
271 + 31503961 = 31504232
349 + 31503883 = 31504232

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.183.104.

Address: 1.224.183.104
Class: public
IPv4-mapped IPv6: ::ffff:1.224.183.104

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.
