Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488876, here are decompositions:

17 + 2147488859 = 2147488876
83 + 2147488793 = 2147488876
149 + 2147488727 = 2147488876
233 + 2147488643 = 2147488876
257 + 2147488619 = 2147488876
263 + 2147488613 = 2147488876
317 + 2147488559 = 2147488876
359 + 2147488517 = 2147488876

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.20.108.

Address: 128.0.20.108
Class: public
IPv4-mapped IPv6: ::ffff:128.0.20.108
