Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486184, here are decompositions:

37 + 2147486147 = 2147486184
73 + 2147486111 = 2147486184
163 + 2147486021 = 2147486184
167 + 2147486017 = 2147486184
257 + 2147485927 = 2147486184
271 + 2147485913 = 2147486184
307 + 2147485877 = 2147486184
313 + 2147485871 = 2147486184

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.9.232.
