Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481842, here are decompositions:

31 + 2147481811 = 2147481842
271 + 2147481571 = 2147481842
313 + 2147481529 = 2147481842
643 + 2147481199 = 2147481842
691 + 2147481151 = 2147481842
811 + 2147481031 = 2147481842
823 + 2147481019 = 2147481842
853 + 2147480989 = 2147481842

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.255.248.242.

Address: 127.255.248.242
