Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489260, here are decompositions:

17 + 2147489243 = 2147489260
53 + 2147489207 = 2147489260
173 + 2147489087 = 2147489260
263 + 2147488997 = 2147489260
347 + 2147488913 = 2147489260
353 + 2147488907 = 2147489260
401 + 2147488859 = 2147489260
467 + 2147488793 = 2147489260

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.21.236.
