Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491532, here are decompositions:

163 + 2147491369 = 2147491532
271 + 2147491261 = 2147491532
283 + 2147491249 = 2147491532
313 + 2147491219 = 2147491532
331 + 2147491201 = 2147491532
409 + 2147491123 = 2147491532
421 + 2147491111 = 2147491532
463 + 2147491069 = 2147491532

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.30.204.

Address: 128.0.30.204
Class: public
IPv4-mapped IPv6: ::ffff:128.0.30.204

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