Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557164, here are decompositions:

101 + 33557063 = 33557164
107 + 33557057 = 33557164
227 + 33556937 = 33557164
317 + 33556847 = 33557164
353 + 33556811 = 33557164
491 + 33556673 = 33557164
593 + 33556571 = 33557164
617 + 33556547 = 33557164

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.10.172.

Address: 2.0.10.172
Class: public
IPv4-mapped IPv6: ::ffff:2.0.10.172

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.
