Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543468, here are decompositions:

17 + 31543451 = 31543468
71 + 31543397 = 31543468
107 + 31543361 = 31543468
137 + 31543331 = 31543468
167 + 31543301 = 31543468
251 + 31543217 = 31543468
389 + 31543079 = 31543468
401 + 31543067 = 31543468

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.80.172.

Address: 1.225.80.172
Class: public
IPv4-mapped IPv6: ::ffff:1.225.80.172

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.
