Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509248, here are decompositions:

5 + 33509243 = 33509248
29 + 33509219 = 33509248
347 + 33508901 = 33509248
389 + 33508859 = 33509248
401 + 33508847 = 33509248
419 + 33508829 = 33509248
431 + 33508817 = 33509248
467 + 33508781 = 33509248

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.79.128.

Address: 1.255.79.128
Class: public
IPv4-mapped IPv6: ::ffff:1.255.79.128

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.
