Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490728, here are decompositions:

139 + 2147490589 = 2147490728
151 + 2147490577 = 2147490728
199 + 2147490529 = 2147490728
241 + 2147490487 = 2147490728
277 + 2147490451 = 2147490728
367 + 2147490361 = 2147490728
499 + 2147490229 = 2147490728
619 + 2147490109 = 2147490728

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.27.168.

Address: 128.0.27.168
Class: public
IPv4-mapped IPv6: ::ffff:128.0.27.168
