Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523240, here are decompositions:

11 + 33523229 = 33523240
29 + 33523211 = 33523240
59 + 33523181 = 33523240
71 + 33523169 = 33523240
131 + 33523109 = 33523240
227 + 33523013 = 33523240
281 + 33522959 = 33523240
293 + 33522947 = 33523240

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.134.40.

Address: 1.255.134.40
Class: public
IPv4-mapped IPv6: ::ffff:1.255.134.40

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.
