Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33625478, here are decompositions:

31 + 33625447 = 33625478
67 + 33625411 = 33625478
109 + 33625369 = 33625478
199 + 33625279 = 33625478
487 + 33624991 = 33625478
547 + 33624931 = 33625478
619 + 33624859 = 33625478
661 + 33624817 = 33625478

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.1.21.134.

Address: 2.1.21.134
Class: public
IPv4-mapped IPv6: ::ffff:2.1.21.134

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.
