Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574246, here are decompositions:

13 + 31574233 = 31574246
43 + 31574203 = 31574246
73 + 31574173 = 31574246
139 + 31574107 = 31574246
199 + 31574047 = 31574246
499 + 31573747 = 31574246
607 + 31573639 = 31574246
619 + 31573627 = 31574246

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.200.230.

Address: 1.225.200.230
Class: public
IPv4-mapped IPv6: ::ffff:1.225.200.230

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.
