Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487448, here are decompositions:

47 + 2147487401 = 2147487448
89 + 2147487359 = 2147487448
179 + 2147487269 = 2147487448
389 + 2147487059 = 2147487448
419 + 2147487029 = 2147487448
467 + 2147486981 = 2147487448
479 + 2147486969 = 2147487448
521 + 2147486927 = 2147487448

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.216.

Address: 128.0.14.216
Class: public
IPv4-mapped IPv6: ::ffff:128.0.14.216
