Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552996, here are decompositions:

53 + 31552943 = 31552996
89 + 31552907 = 31552996
113 + 31552883 = 31552996
149 + 31552847 = 31552996
179 + 31552817 = 31552996
263 + 31552733 = 31552996
269 + 31552727 = 31552996
353 + 31552643 = 31552996

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.117.228.

Address: 1.225.117.228
Class: public
IPv4-mapped IPv6: ::ffff:1.225.117.228

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.
