Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487244, here are decompositions:

17 + 2147487227 = 2147487244
41 + 2147487203 = 2147487244
131 + 2147487113 = 2147487244
167 + 2147487077 = 2147487244
263 + 2147486981 = 2147487244
317 + 2147486927 = 2147487244
401 + 2147486843 = 2147487244
503 + 2147486741 = 2147487244

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.12.

Address: 128.0.14.12
Class: public
IPv4-mapped IPv6: ::ffff:128.0.14.12
