Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620800, here are decompositions:

11 + 33620789 = 33620800
173 + 33620627 = 33620800
179 + 33620621 = 33620800
263 + 33620537 = 33620800
293 + 33620507 = 33620800
419 + 33620381 = 33620800
443 + 33620357 = 33620800
449 + 33620351 = 33620800

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.1.3.64.

Address: 2.1.3.64
Class: public
IPv4-mapped IPv6: ::ffff:2.1.3.64

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.
