Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471996, here are decompositions:

5 + 31471991 = 31471996
29 + 31471967 = 31471996
89 + 31471907 = 31471996
113 + 31471883 = 31471996
173 + 31471823 = 31471996
197 + 31471799 = 31471996
233 + 31471763 = 31471996
293 + 31471703 = 31471996

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.224.57.124.

Address: 1.224.57.124
Class: public
IPv4-mapped IPv6: ::ffff:1.224.57.124

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.
