Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487986, here are decompositions:

79 + 2147487907 = 2147487986
157 + 2147487829 = 2147487986
229 + 2147487757 = 2147487986
283 + 2147487703 = 2147487986
337 + 2147487649 = 2147487986
349 + 2147487637 = 2147487986
379 + 2147487607 = 2147487986
577 + 2147487409 = 2147487986

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.16.242.

Address: 128.0.16.242
