Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500138, here are decompositions:

11 + 2147500127 = 2147500138
89 + 2147500049 = 2147500138
131 + 2147500007 = 2147500138
149 + 2147499989 = 2147500138
431 + 2147499707 = 2147500138
467 + 2147499671 = 2147500138
521 + 2147499617 = 2147500138
599 + 2147499539 = 2147500138

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.64.106.

Address: 128.0.64.106
Class: public
IPv4-mapped IPv6: ::ffff:128.0.64.106

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