Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605540, here are decompositions:

61 + 33605479 = 33605540
97 + 33605443 = 33605540
151 + 33605389 = 33605540
271 + 33605269 = 33605540
277 + 33605263 = 33605540
313 + 33605227 = 33605540
499 + 33605041 = 33605540
523 + 33605017 = 33605540

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.199.164.

Address: 2.0.199.164
Class: public
IPv4-mapped IPv6: ::ffff:2.0.199.164

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.
