Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483844, here are decompositions:

31 + 2147483813 = 2147483844
61 + 2147483783 = 2147483844
67 + 2147483777 = 2147483844
101 + 2147483743 = 2147483844
131 + 2147483713 = 2147483844
151 + 2147483693 = 2147483844
197 + 2147483647 = 2147483844
257 + 2147483587 = 2147483844

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.0.196.

Address: 128.0.0.196
Class: public
IPv4-mapped IPv6: ::ffff:128.0.0.196
