Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523242, here are decompositions:

5 + 31523237 = 31523242
11 + 31523231 = 31523242
41 + 31523201 = 31523242
131 + 31523111 = 31523242
239 + 31523003 = 31523242
263 + 31522979 = 31523242
281 + 31522961 = 31523242
353 + 31522889 = 31523242

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.1.170.

Address: 1.225.1.170
Class: public
IPv4-mapped IPv6: ::ffff:1.225.1.170

Public, routable address (assignable to a host on the internet).

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
