Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608660, here are decompositions:

13 + 33608647 = 33608660
31 + 33608629 = 33608660
79 + 33608581 = 33608660
97 + 33608563 = 33608660
193 + 33608467 = 33608660
223 + 33608437 = 33608660
271 + 33608389 = 33608660
277 + 33608383 = 33608660

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.211.212.

Address: 2.0.211.212
Class: public
IPv4-mapped IPv6: ::ffff:2.0.211.212

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.
