Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608864, here are decompositions:

7 + 33608857 = 33608864
127 + 33608737 = 33608864
181 + 33608683 = 33608864
283 + 33608581 = 33608864
337 + 33608527 = 33608864
397 + 33608467 = 33608864
547 + 33608317 = 33608864
571 + 33608293 = 33608864

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.212.160.

Address: 2.0.212.160
Class: public
IPv4-mapped IPv6: ::ffff:2.0.212.160

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.
