Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33617428, here are decompositions:

17 + 33617411 = 33617428
107 + 33617321 = 33617428
137 + 33617291 = 33617428
167 + 33617261 = 33617428
269 + 33617159 = 33617428
359 + 33617069 = 33617428
461 + 33616967 = 33617428
521 + 33616907 = 33617428

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.246.20.

Address: 2.0.246.20
Class: public
IPv4-mapped IPv6: ::ffff:2.0.246.20

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