Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33564872, here are decompositions:

13 + 33564859 = 33564872
193 + 33564679 = 33564872
199 + 33564673 = 33564872
241 + 33564631 = 33564872
331 + 33564541 = 33564872
409 + 33564463 = 33564872
541 + 33564331 = 33564872
643 + 33564229 = 33564872

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.40.200.

Address: 2.0.40.200
Class: public
IPv4-mapped IPv6: ::ffff:2.0.40.200

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.
