Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522942, here are decompositions:

5 + 31522937 = 31522942
41 + 31522901 = 31522942
53 + 31522889 = 31522942
359 + 31522583 = 31522942
389 + 31522553 = 31522942
401 + 31522541 = 31522942
419 + 31522523 = 31522942
449 + 31522493 = 31522942

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.0.126.

Address: 1.225.0.126
Class: public
IPv4-mapped IPv6: ::ffff:1.225.0.126

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.
