Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491004, here are decompositions:

3 + 2147491001 = 2147491004
7 + 2147490997 = 2147491004
31 + 2147490973 = 2147491004
37 + 2147490967 = 2147491004
193 + 2147490811 = 2147491004
277 + 2147490727 = 2147491004
541 + 2147490463 = 2147491004
643 + 2147490361 = 2147491004

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.28.188.

Address: 128.0.28.188
Class: public
IPv4-mapped IPv6: ::ffff:128.0.28.188
