Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571072, here are decompositions:

23 + 33571049 = 33571072
173 + 33570899 = 33571072
191 + 33570881 = 33571072
239 + 33570833 = 33571072
263 + 33570809 = 33571072
383 + 33570689 = 33571072
449 + 33570623 = 33571072
461 + 33570611 = 33571072

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.65.0.

Address: 2.0.65.0
Class: public
IPv4-mapped IPv6: ::ffff:2.0.65.0

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.
