Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487374, here are decompositions:

31 + 2147487343 = 2147487374
73 + 2147487301 = 2147487374
127 + 2147487247 = 2147487374
523 + 2147486851 = 2147487374
547 + 2147486827 = 2147487374
733 + 2147486641 = 2147487374
757 + 2147486617 = 2147487374
787 + 2147486587 = 2147487374

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.14.142.

Address: 128.0.14.142
