Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489146, here are decompositions:

3 + 2147489143 = 2147489146
59 + 2147489087 = 2147489146
149 + 2147488997 = 2147489146
227 + 2147488919 = 2147489146
233 + 2147488913 = 2147489146
239 + 2147488907 = 2147489146
353 + 2147488793 = 2147489146
419 + 2147488727 = 2147489146

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.21.122.

Address: 128.0.21.122
