Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472746, here are decompositions:

23 + 31472723 = 31472746
47 + 31472699 = 31472746
83 + 31472663 = 31472746
113 + 31472633 = 31472746
257 + 31472489 = 31472746
563 + 31472183 = 31472746
587 + 31472159 = 31472746
593 + 31472153 = 31472746

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.60.106.

Address: 1.224.60.106
Class: public
IPv4-mapped IPv6: ::ffff:1.224.60.106

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.
