Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491040, here are decompositions:

3 + 2147491037 = 2147491040
7 + 2147491033 = 2147491040
43 + 2147490997 = 2147491040
67 + 2147490973 = 2147491040
73 + 2147490967 = 2147491040
157 + 2147490883 = 2147491040
229 + 2147490811 = 2147491040
241 + 2147490799 = 2147491040

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.28.224.

Address: 128.0.28.224
Class: public
IPv4-mapped IPv6: ::ffff:128.0.28.224

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