Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473952, here are decompositions:

89 + 31473863 = 31473952
113 + 31473839 = 31473952
173 + 31473779 = 31473952
353 + 31473599 = 31473952
359 + 31473593 = 31473952
593 + 31473359 = 31473952
701 + 31473251 = 31473952
743 + 31473209 = 31473952

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.65.32.

Address: 1.224.65.32
Class: public
IPv4-mapped IPv6: ::ffff:1.224.65.32

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.
