Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33580940, here are decompositions:

31 + 33580909 = 33580940
37 + 33580903 = 33580940
61 + 33580879 = 33580940
139 + 33580801 = 33580940
163 + 33580777 = 33580940
199 + 33580741 = 33580940
271 + 33580669 = 33580940
307 + 33580633 = 33580940

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.103.140.

Address: 2.0.103.140
Class: public
IPv4-mapped IPv6: ::ffff:2.0.103.140

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.
