Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600372, here are decompositions:

53 + 31600319 = 31600372
71 + 31600301 = 31600372
113 + 31600259 = 31600372
179 + 31600193 = 31600372
239 + 31600133 = 31600372
269 + 31600103 = 31600372
311 + 31600061 = 31600372
431 + 31599941 = 31600372

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.46.244.

Address: 1.226.46.244
Class: public
IPv4-mapped IPv6: ::ffff:1.226.46.244

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.
