Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447496, here are decompositions:

19 + 31447477 = 31447496
103 + 31447393 = 31447496
139 + 31447357 = 31447496
163 + 31447333 = 31447496
229 + 31447267 = 31447496
307 + 31447189 = 31447496
397 + 31447099 = 31447496
499 + 31446997 = 31447496

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.223.217.200.

Address: 1.223.217.200
Class: public
IPv4-mapped IPv6: ::ffff:1.223.217.200

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.
