Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490678, here are decompositions:

19 + 2147490659 = 2147490678
89 + 2147490589 = 2147490678
97 + 2147490581 = 2147490678
101 + 2147490577 = 2147490678
139 + 2147490539 = 2147490678
149 + 2147490529 = 2147490678
191 + 2147490487 = 2147490678
227 + 2147490451 = 2147490678

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.27.118.

Address: 128.0.27.118
Class: public
IPv4-mapped IPv6: ::ffff:128.0.27.118
