Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491604, here are decompositions:

7 + 2147491597 = 2147491604
31 + 2147491573 = 2147491604
61 + 2147491543 = 2147491604
67 + 2147491537 = 2147491604
127 + 2147491477 = 2147491604
331 + 2147491273 = 2147491604
367 + 2147491237 = 2147491604
523 + 2147491081 = 2147491604

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.31.20.

Address: 128.0.31.20
Class: public
IPv4-mapped IPv6: ::ffff:128.0.31.20

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