Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528742, here are decompositions:

13 + 31528729 = 31528742
19 + 31528723 = 31528742
73 + 31528669 = 31528742
109 + 31528633 = 31528742
163 + 31528579 = 31528742
211 + 31528531 = 31528742
241 + 31528501 = 31528742
283 + 31528459 = 31528742

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.23.38.

Address: 1.225.23.38
Class: public
IPv4-mapped IPv6: ::ffff:1.225.23.38

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.

Routing number

Federal Reserve

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.
