Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542472, here are decompositions:

53 + 31542419 = 31542472
113 + 31542359 = 31542472
131 + 31542341 = 31542472
149 + 31542323 = 31542472
191 + 31542281 = 31542472
239 + 31542233 = 31542472
359 + 31542113 = 31542472
389 + 31542083 = 31542472

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.76.200.

Address: 1.225.76.200
Class: public
IPv4-mapped IPv6: ::ffff:1.225.76.200

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.

Federal Reserve district 3 (Philadelphia)

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