Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592846, here are decompositions:

3 + 31592843 = 31592846
13 + 31592833 = 31592846
37 + 31592809 = 31592846
67 + 31592779 = 31592846
73 + 31592773 = 31592846
163 + 31592683 = 31592846
379 + 31592467 = 31592846
409 + 31592437 = 31592846

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.17.142.

Address: 1.226.17.142
Class: public
IPv4-mapped IPv6: ::ffff:1.226.17.142

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.
