Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536242, here are decompositions:

19 + 31536223 = 31536242
181 + 31536061 = 31536242
193 + 31536049 = 31536242
223 + 31536019 = 31536242
421 + 31535821 = 31536242
433 + 31535809 = 31536242
571 + 31535671 = 31536242
691 + 31535551 = 31536242

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.52.114.

Address: 1.225.52.114
Class: public
IPv4-mapped IPv6: ::ffff:1.225.52.114

Federal Reserve district 3 (Philadelphia)

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
