Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33611660, here are decompositions:

7 + 33611653 = 33611660
31 + 33611629 = 33611660
163 + 33611497 = 33611660
193 + 33611467 = 33611660
211 + 33611449 = 33611660
307 + 33611353 = 33611660
349 + 33611311 = 33611660
367 + 33611293 = 33611660

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.223.140.

Address: 2.0.223.140
Class: public
IPv4-mapped IPv6: ::ffff:2.0.223.140

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.
