Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33480040, here are decompositions:

17 + 33480023 = 33480040
131 + 33479909 = 33480040
179 + 33479861 = 33480040
227 + 33479813 = 33480040
233 + 33479807 = 33480040
263 + 33479777 = 33480040
281 + 33479759 = 33480040
353 + 33479687 = 33480040

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.221.104.

Address: 1.254.221.104
Class: public
IPv4-mapped IPv6: ::ffff:1.254.221.104

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.
