Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489852, here are decompositions:

3 + 2147489849 = 2147489852
31 + 2147489821 = 2147489852
139 + 2147489713 = 2147489852
199 + 2147489653 = 2147489852
349 + 2147489503 = 2147489852
379 + 2147489473 = 2147489852
709 + 2147489143 = 2147489852
769 + 2147489083 = 2147489852

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.24.60.
