Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550640, here are decompositions:

7 + 33550633 = 33550640
73 + 33550567 = 33550640
127 + 33550513 = 33550640
139 + 33550501 = 33550640
199 + 33550441 = 33550640
313 + 33550327 = 33550640
373 + 33550267 = 33550640
439 + 33550201 = 33550640

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.241.48.

Address: 1.255.241.48
Class: public
IPv4-mapped IPv6: ::ffff:1.255.241.48

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.
