Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489986, here are decompositions:

7 + 33489979 = 33489986
43 + 33489943 = 33489986
109 + 33489877 = 33489986
157 + 33489829 = 33489986
223 + 33489763 = 33489986
337 + 33489649 = 33489986
367 + 33489619 = 33489986
373 + 33489613 = 33489986

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 1.255.4.66.

Address: 1.255.4.66
Class: public
IPv4-mapped IPv6: ::ffff:1.255.4.66

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