Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587642, here are decompositions:

61 + 33587581 = 33587642
139 + 33587503 = 33587642
163 + 33587479 = 33587642
241 + 33587401 = 33587642
271 + 33587371 = 33587642
331 + 33587311 = 33587642
379 + 33587263 = 33587642
409 + 33587233 = 33587642

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.129.186.

Address: 2.0.129.186
Class: public
IPv4-mapped IPv6: ::ffff:2.0.129.186

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