Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561956, here are decompositions:

3 + 33561953 = 33561956
7 + 33561949 = 33561956
13 + 33561943 = 33561956
37 + 33561919 = 33561956
79 + 33561877 = 33561956
139 + 33561817 = 33561956
157 + 33561799 = 33561956
277 + 33561679 = 33561956

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.29.100.

Address: 2.0.29.100
Class: public
IPv4-mapped IPv6: ::ffff:2.0.29.100

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