Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487670, here are decompositions:

47 + 2147487623 = 2147487670
59 + 2147487611 = 2147487670
71 + 2147487599 = 2147487670
197 + 2147487473 = 2147487670
269 + 2147487401 = 2147487670
311 + 2147487359 = 2147487670
401 + 2147487269 = 2147487670
443 + 2147487227 = 2147487670

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.15.182.

Address: 128.0.15.182
Class: public
IPv4-mapped IPv6: ::ffff:128.0.15.182
