Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485388, here are decompositions:

7 + 2147485381 = 2147485388
19 + 2147485369 = 2147485388
31 + 2147485357 = 2147485388
79 + 2147485309 = 2147485388
127 + 2147485261 = 2147485388
199 + 2147485189 = 2147485388
331 + 2147485057 = 2147485388
397 + 2147484991 = 2147485388

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.6.204.

Address: 128.0.6.204
Class: public
IPv4-mapped IPv6: ::ffff:128.0.6.204

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