Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487548, here are decompositions:

7 + 2147487541 = 2147487548
97 + 2147487451 = 2147487548
139 + 2147487409 = 2147487548
379 + 2147487169 = 2147487548
499 + 2147487049 = 2147487548
691 + 2147486857 = 2147487548
757 + 2147486791 = 2147487548
859 + 2147486689 = 2147487548

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.15.60.

Address: 128.0.15.60
Class: public
IPv4-mapped IPv6: ::ffff:128.0.15.60

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