Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520984, here are decompositions:

5 + 33520979 = 33520984
11 + 33520973 = 33520984
17 + 33520967 = 33520984
137 + 33520847 = 33520984
317 + 33520667 = 33520984
587 + 33520397 = 33520984
617 + 33520367 = 33520984
701 + 33520283 = 33520984

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.125.88.

Address: 1.255.125.88
Class: public
IPv4-mapped IPv6: ::ffff:1.255.125.88

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