Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617352, here are decompositions:

23 + 31617329 = 31617352
59 + 31617293 = 31617352
71 + 31617281 = 31617352
83 + 31617269 = 31617352
101 + 31617251 = 31617352
113 + 31617239 = 31617352
251 + 31617101 = 31617352
353 + 31616999 = 31617352

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.113.72.

Address: 1.226.113.72
Class: public
IPv4-mapped IPv6: ::ffff:1.226.113.72

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.
