Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33475660, here are decompositions:

47 + 33475613 = 33475660
89 + 33475571 = 33475660
107 + 33475553 = 33475660
137 + 33475523 = 33475660
227 + 33475433 = 33475660
233 + 33475427 = 33475660
347 + 33475313 = 33475660
353 + 33475307 = 33475660

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.254.204.76.

Address: 1.254.204.76
Class: public
IPv4-mapped IPv6: ::ffff:1.254.204.76

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.
