Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463470, here are decompositions:

11 + 31463459 = 31463470
41 + 31463429 = 31463470
83 + 31463387 = 31463470
107 + 31463363 = 31463470
149 + 31463321 = 31463470
257 + 31463213 = 31463470
347 + 31463123 = 31463470
383 + 31463087 = 31463470

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.24.46.

Address: 1.224.24.46
Class: public
IPv4-mapped IPv6: ::ffff:1.224.24.46

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.
