Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483812, here are decompositions:

29 + 2147483783 = 2147483812
233 + 2147483579 = 2147483812
263 + 2147483549 = 2147483812
269 + 2147483543 = 2147483812
389 + 2147483423 = 2147483812
563 + 2147483249 = 2147483812
641 + 2147483171 = 2147483812
743 + 2147483069 = 2147483812

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.0.164.
