Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613668, here are decompositions:

7 + 33613661 = 33613668
31 + 33613637 = 33613668
47 + 33613621 = 33613668
71 + 33613597 = 33613668
97 + 33613571 = 33613668
107 + 33613561 = 33613668
131 + 33613537 = 33613668
191 + 33613477 = 33613668

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.231.100.

Address: 2.0.231.100
Class: public
IPv4-mapped IPv6: ::ffff:2.0.231.100

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