Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607032, here are decompositions:

53 + 31606979 = 31607032
59 + 31606973 = 31607032
89 + 31606943 = 31607032
101 + 31606931 = 31607032
113 + 31606919 = 31607032
389 + 31606643 = 31607032
449 + 31606583 = 31607032
491 + 31606541 = 31607032

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.226.72.248.

Address: 1.226.72.248
Class: public
IPv4-mapped IPv6: ::ffff:1.226.72.248

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.
