Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535104, here are decompositions:

23 + 31535081 = 31535104
47 + 31535057 = 31535104
71 + 31535033 = 31535104
191 + 31534913 = 31535104
233 + 31534871 = 31535104
317 + 31534787 = 31535104
347 + 31534757 = 31535104
353 + 31534751 = 31535104

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.225.48.0.

Address: 1.225.48.0
Class: public
IPv4-mapped IPv6: ::ffff:1.225.48.0

Public, routable address (assignable to a host on the internet).
