Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587370, here are decompositions:

7 + 33587363 = 33587370
13 + 33587357 = 33587370
23 + 33587347 = 33587370
31 + 33587339 = 33587370
59 + 33587311 = 33587370
67 + 33587303 = 33587370
83 + 33587287 = 33587370
107 + 33587263 = 33587370

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.128.170.

Address: 2.0.128.170
Class: public
IPv4-mapped IPv6: ::ffff:2.0.128.170

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.
