Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490274, here are decompositions:

11 + 2147490263 = 2147490274
113 + 2147490161 = 2147490274
197 + 2147490077 = 2147490274
263 + 2147490011 = 2147490274
317 + 2147489957 = 2147490274
401 + 2147489873 = 2147490274
431 + 2147489843 = 2147490274
557 + 2147489717 = 2147490274

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.25.226.

Address: 128.0.25.226
Class: public
IPv4-mapped IPv6: ::ffff:128.0.25.226
