Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556660, here are decompositions:

47 + 33556613 = 33556660
89 + 33556571 = 33556660
101 + 33556559 = 33556660
113 + 33556547 = 33556660
131 + 33556529 = 33556660
167 + 33556493 = 33556660
257 + 33556403 = 33556660
317 + 33556343 = 33556660

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.8.180.

Address: 2.0.8.180
Class: public
IPv4-mapped IPv6: ::ffff:2.0.8.180

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