Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555768, here are decompositions:

11 + 33555757 = 33555768
17 + 33555751 = 33555768
31 + 33555737 = 33555768
41 + 33555727 = 33555768
67 + 33555701 = 33555768
89 + 33555679 = 33555768
101 + 33555667 = 33555768
107 + 33555661 = 33555768

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.5.56.

Address: 2.0.5.56
Class: public
IPv4-mapped IPv6: ::ffff:2.0.5.56

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.
