Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446824, here are decompositions:

67 + 31446757 = 31446824
271 + 31446553 = 31446824
397 + 31446427 = 31446824
457 + 31446367 = 31446824
463 + 31446361 = 31446824
571 + 31446253 = 31446824
601 + 31446223 = 31446824
613 + 31446211 = 31446824

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.223.215.40.

Address: 1.223.215.40
Class: public
IPv4-mapped IPv6: ::ffff:1.223.215.40

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.
