Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33506940, here are decompositions:

37 + 33506903 = 33506940
43 + 33506897 = 33506940
83 + 33506857 = 33506940
139 + 33506801 = 33506940
163 + 33506777 = 33506940
167 + 33506773 = 33506940
199 + 33506741 = 33506940
251 + 33506689 = 33506940

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.70.124.

Address: 1.255.70.124
Class: public
IPv4-mapped IPv6: ::ffff:1.255.70.124

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