Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525622, here are decompositions:

13 + 31525609 = 31525622
19 + 31525603 = 31525622
379 + 31525243 = 31525622
409 + 31525213 = 31525622
421 + 31525201 = 31525622
439 + 31525183 = 31525622
631 + 31524991 = 31525622
829 + 31524793 = 31525622

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.10.246.

Address: 1.225.10.246
Class: public
IPv4-mapped IPv6: ::ffff:1.225.10.246

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.

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