Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488618, here are decompositions:

5 + 2147488613 = 2147488618
59 + 2147488559 = 2147488618
101 + 2147488517 = 2147488618
311 + 2147488307 = 2147488618
467 + 2147488151 = 2147488618
557 + 2147488061 = 2147488618
617 + 2147488001 = 2147488618
677 + 2147487941 = 2147488618

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.19.106.

Address: 128.0.19.106
