Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491070, here are decompositions:

3 + 2147491067 = 2147491070
37 + 2147491033 = 2147491070
73 + 2147490997 = 2147491070
97 + 2147490973 = 2147491070
103 + 2147490967 = 2147491070
199 + 2147490871 = 2147491070
271 + 2147490799 = 2147491070
331 + 2147490739 = 2147491070

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.28.254.

Address: 128.0.28.254
Class: public
IPv4-mapped IPv6: ::ffff:128.0.28.254
