Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484028, here are decompositions:

29 + 2147483999 = 2147484028
251 + 2147483777 = 2147484028
449 + 2147483579 = 2147484028
479 + 2147483549 = 2147484028
857 + 2147483171 = 2147484028
1091 + 2147482937 = 2147484028
1151 + 2147482877 = 2147484028
1217 + 2147482811 = 2147484028

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.1.124.

Address: 128.0.1.124
Class: public
IPv4-mapped IPv6: ::ffff:128.0.1.124

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