Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490372, here are decompositions:

11 + 2147490361 = 2147490372
29 + 2147490343 = 2147490372
89 + 2147490283 = 2147490372
109 + 2147490263 = 2147490372
211 + 2147490161 = 2147490372
263 + 2147490109 = 2147490372
283 + 2147490089 = 2147490372
311 + 2147490061 = 2147490372

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.26.68.

Address: 128.0.26.68
Class: public
IPv4-mapped IPv6: ::ffff:128.0.26.68
