Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555988, here are decompositions:

17 + 33555971 = 33555988
29 + 33555959 = 33555988
41 + 33555947 = 33555988
251 + 33555737 = 33555988
359 + 33555629 = 33555988
461 + 33555527 = 33555988
491 + 33555497 = 33555988
569 + 33555419 = 33555988

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.6.20.

Address: 2.0.6.20
Class: public
IPv4-mapped IPv6: ::ffff:2.0.6.20

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