Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596460, here are decompositions:

23 + 31596437 = 31596460
41 + 31596419 = 31596460
47 + 31596413 = 31596460
59 + 31596401 = 31596460
149 + 31596311 = 31596460
167 + 31596293 = 31596460
251 + 31596209 = 31596460
317 + 31596143 = 31596460

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.31.172.

Address: 1.226.31.172
Class: public
IPv4-mapped IPv6: ::ffff:1.226.31.172

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.
