Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521624, here are decompositions:

163 + 33521461 = 33521624
193 + 33521431 = 33521624
223 + 33521401 = 33521624
541 + 33521083 = 33521624
733 + 33520891 = 33521624
811 + 33520813 = 33521624
823 + 33520801 = 33521624
937 + 33520687 = 33521624

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.127.216.

Address: 1.255.127.216
Class: public
IPv4-mapped IPv6: ::ffff:1.255.127.216

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.
