Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521080, here are decompositions:

23 + 33521057 = 33521080
41 + 33521039 = 33521080
59 + 33521021 = 33521080
71 + 33521009 = 33521080
101 + 33520979 = 33521080
107 + 33520973 = 33521080
113 + 33520967 = 33521080
233 + 33520847 = 33521080

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.125.184.

Address: 1.255.125.184
Class: public
IPv4-mapped IPv6: ::ffff:1.255.125.184

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.
