Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488642, here are decompositions:

23 + 2147488619 = 2147488642
29 + 2147488613 = 2147488642
83 + 2147488559 = 2147488642
479 + 2147488163 = 2147488642
491 + 2147488151 = 2147488642
599 + 2147488043 = 2147488642
641 + 2147488001 = 2147488642
701 + 2147487941 = 2147488642

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.19.130.

Address: 128.0.19.130
