Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469746, here are decompositions:

5 + 31469741 = 31469746
23 + 31469723 = 31469746
167 + 31469579 = 31469746
227 + 31469519 = 31469746
233 + 31469513 = 31469746
359 + 31469387 = 31469746
389 + 31469357 = 31469746
419 + 31469327 = 31469746

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.48.178.

Address: 1.224.48.178
Class: public
IPv4-mapped IPv6: ::ffff:1.224.48.178

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.
