Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586344, here are decompositions:

5 + 31586339 = 31586344
71 + 31586273 = 31586344
107 + 31586237 = 31586344
173 + 31586171 = 31586344
197 + 31586147 = 31586344
347 + 31585997 = 31586344
521 + 31585823 = 31586344
563 + 31585781 = 31586344

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.248.40.

Address: 1.225.248.40
Class: public
IPv4-mapped IPv6: ::ffff:1.225.248.40

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.
