Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503972, here are decompositions:

3 + 33503969 = 33503972
31 + 33503941 = 33503972
193 + 33503779 = 33503972
199 + 33503773 = 33503972
223 + 33503749 = 33503972
283 + 33503689 = 33503972
331 + 33503641 = 33503972
373 + 33503599 = 33503972

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.58.228.

Address: 1.255.58.228
Class: public
IPv4-mapped IPv6: ::ffff:1.255.58.228

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