Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484840, here are decompositions:

19 + 2147484821 = 2147484840
89 + 2147484751 = 2147484840
107 + 2147484733 = 2147484840
199 + 2147484641 = 2147484840
223 + 2147484617 = 2147484840
227 + 2147484613 = 2147484840
229 + 2147484611 = 2147484840
239 + 2147484601 = 2147484840

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.4.168.

Address: 128.0.4.168
Class: public
IPv4-mapped IPv6: ::ffff:128.0.4.168
