Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488364, here are decompositions:

31 + 2147488333 = 2147488364
193 + 2147488171 = 2147488364
211 + 2147488153 = 2147488364
337 + 2147488027 = 2147488364
433 + 2147487931 = 2147488364
457 + 2147487907 = 2147488364
547 + 2147487817 = 2147488364
607 + 2147487757 = 2147488364

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.18.108.

Address: 128.0.18.108
