Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443708, here are decompositions:

29 + 2147443679 = 2147443708
317 + 2147443391 = 2147443708
587 + 2147443121 = 2147443708
659 + 2147443049 = 2147443708
719 + 2147442989 = 2147443708
857 + 2147442851 = 2147443708
881 + 2147442827 = 2147443708
911 + 2147442797 = 2147443708

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.99.252.

Address: 127.255.99.252
