Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474346, here are decompositions:

3 + 31474343 = 31474346
97 + 31474249 = 31474346
313 + 31474033 = 31474346
439 + 31473907 = 31474346
499 + 31473847 = 31474346
613 + 31473733 = 31474346
643 + 31473703 = 31474346
823 + 31473523 = 31474346

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.66.170.

Address: 1.224.66.170
Class: public
IPv4-mapped IPv6: ::ffff:1.224.66.170

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.
