Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507664, here are decompositions:

17 + 33507647 = 33507664
23 + 33507641 = 33507664
41 + 33507623 = 33507664
53 + 33507611 = 33507664
101 + 33507563 = 33507664
251 + 33507413 = 33507664
257 + 33507407 = 33507664
263 + 33507401 = 33507664

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.73.80.

Address: 1.255.73.80
Class: public
IPv4-mapped IPv6: ::ffff:1.255.73.80

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.
