Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489350, here are decompositions:

3 + 2147489347 = 2147489350
53 + 2147489297 = 2147489350
59 + 2147489291 = 2147489350
107 + 2147489243 = 2147489350
263 + 2147489087 = 2147489350
353 + 2147488997 = 2147489350
431 + 2147488919 = 2147489350
443 + 2147488907 = 2147489350

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.22.70.
