Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490940, here are decompositions:

17 + 2147490923 = 2147490940
41 + 2147490899 = 2147490940
107 + 2147490833 = 2147490940
167 + 2147490773 = 2147490940
251 + 2147490689 = 2147490940
281 + 2147490659 = 2147490940
347 + 2147490593 = 2147490940
359 + 2147490581 = 2147490940

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.28.124.

Address: 128.0.28.124
Class: public
IPv4-mapped IPv6: ::ffff:128.0.28.124
