Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488636, here are decompositions:

17 + 2147488619 = 2147488636
23 + 2147488613 = 2147488636
389 + 2147488247 = 2147488636
569 + 2147488067 = 2147488636
593 + 2147488043 = 2147488636
809 + 2147487827 = 2147488636
857 + 2147487779 = 2147488636
863 + 2147487773 = 2147488636

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.19.124.

Address: 128.0.19.124
