Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622664, here are decompositions:

23 + 31622641 = 31622664
127 + 31622537 = 31622664
173 + 31622491 = 31622664
191 + 31622473 = 31622664
197 + 31622467 = 31622664
317 + 31622347 = 31622664
383 + 31622281 = 31622664
457 + 31622207 = 31622664

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.134.8.

Address: 1.226.134.8
Class: public
IPv4-mapped IPv6: ::ffff:1.226.134.8

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.
