Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618388, here are decompositions:

29 + 33618359 = 33618388
59 + 33618329 = 33618388
71 + 33618317 = 33618388
137 + 33618251 = 33618388
179 + 33618209 = 33618388
197 + 33618191 = 33618388
227 + 33618161 = 33618388
239 + 33618149 = 33618388

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.249.212.

Address: 2.0.249.212
Class: public
IPv4-mapped IPv6: ::ffff:2.0.249.212

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.
