Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489164, here are decompositions:

167 + 2147488997 = 2147489164
251 + 2147488913 = 2147489164
257 + 2147488907 = 2147489164
521 + 2147488643 = 2147489164
647 + 2147488517 = 2147489164
857 + 2147488307 = 2147489164
1013 + 2147488151 = 2147489164
1097 + 2147488067 = 2147489164

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.21.140.

Address: 128.0.21.140
Class: public
IPv4-mapped IPv6: ::ffff:128.0.21.140
