Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621964, here are decompositions:

41 + 33621923 = 33621964
53 + 33621911 = 33621964
83 + 33621881 = 33621964
107 + 33621857 = 33621964
251 + 33621713 = 33621964
353 + 33621611 = 33621964
491 + 33621473 = 33621964
557 + 33621407 = 33621964

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.1.7.204.

Address: 2.1.7.204
Class: public
IPv4-mapped IPv6: ::ffff:2.1.7.204

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.
