Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597896, here are decompositions:

17 + 31597879 = 31597896
19 + 31597877 = 31597896
23 + 31597873 = 31597896
53 + 31597843 = 31597896
73 + 31597823 = 31597896
103 + 31597793 = 31597896
157 + 31597739 = 31597896
167 + 31597729 = 31597896

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.37.72.

Address: 1.226.37.72
Class: public
IPv4-mapped IPv6: ::ffff:1.226.37.72

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.
