Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487846, here are decompositions:

13 + 2147487833 = 2147487846
17 + 2147487829 = 2147487846
19 + 2147487827 = 2147487846
29 + 2147487817 = 2147487846
43 + 2147487803 = 2147487846
47 + 2147487799 = 2147487846
67 + 2147487779 = 2147487846
73 + 2147487773 = 2147487846

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.16.102.

Address: 128.0.16.102
