Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613228, here are decompositions:

17 + 33613211 = 33613228
41 + 33613187 = 33613228
59 + 33613169 = 33613228
101 + 33613127 = 33613228
149 + 33613079 = 33613228
179 + 33613049 = 33613228
197 + 33613031 = 33613228
251 + 33612977 = 33613228

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.229.172.

Address: 2.0.229.172
Class: public
IPv4-mapped IPv6: ::ffff:2.0.229.172

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.
