Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521608, here are decompositions:

59 + 33521549 = 33521608
137 + 33521471 = 33521608
191 + 33521417 = 33521608
389 + 33521219 = 33521608
431 + 33521177 = 33521608
467 + 33521141 = 33521608
509 + 33521099 = 33521608
521 + 33521087 = 33521608

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.127.200.

Address: 1.255.127.200
Class: public
IPv4-mapped IPv6: ::ffff:1.255.127.200

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.
