Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483820, here are decompositions:

7 + 2147483813 = 2147483820
37 + 2147483783 = 2147483820
43 + 2147483777 = 2147483820
107 + 2147483713 = 2147483820
127 + 2147483693 = 2147483820
173 + 2147483647 = 2147483820
191 + 2147483629 = 2147483820
233 + 2147483587 = 2147483820

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.0.172.

Address: 128.0.0.172
Class: public
IPv4-mapped IPv6: ::ffff:128.0.0.172
