Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561846, here are decompositions:

7 + 33561839 = 33561846
29 + 33561817 = 33561846
47 + 33561799 = 33561846
67 + 33561779 = 33561846
79 + 33561767 = 33561846
103 + 33561743 = 33561846
127 + 33561719 = 33561846
167 + 33561679 = 33561846

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.28.246.

Address: 2.0.28.246
Class: public
IPv4-mapped IPv6: ::ffff:2.0.28.246

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