Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532482, here are decompositions:

5 + 31532477 = 31532482
53 + 31532429 = 31532482
263 + 31532219 = 31532482
419 + 31532063 = 31532482
461 + 31532021 = 31532482
479 + 31532003 = 31532482
599 + 31531883 = 31532482
1061 + 31531421 = 31532482

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.37.194.

Address: 1.225.37.194
Class: public
IPv4-mapped IPv6: ::ffff:1.225.37.194

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.
