Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460392, here are decompositions:

23 + 31460369 = 31460392
53 + 31460339 = 31460392
71 + 31460321 = 31460392
101 + 31460291 = 31460392
113 + 31460279 = 31460392
263 + 31460129 = 31460392
443 + 31459949 = 31460392
461 + 31459931 = 31460392

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.12.40.

Address: 1.224.12.40
Class: public
IPv4-mapped IPv6: ::ffff:1.224.12.40

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.
